What Does a Baby Boy Look Like at 20 Weeks

1. Baby'due south heart rate is slower than 140 beats per minute
This test of a baby's sex suggests that if the heart is pumping faster than 140 beats per infinitesimal, you will be having a girl. Although information technology sounds like a medical diagnosis, in fact when a study was carried out from 1997 to 2003 on 477 bubs tested in the first 12 weeks, the boys' hearts clocked in a piddling bit faster at 154.9 beats per minute while the girls strolled in at a leisurely 151.7.
Really, this difference isn't statistically significant. The study just showed all babies should accept a heart charge per unit over 140 beats per minute in the first trimester, regardless of their sex. The middle rate slows down every bit the pregnancy progresses.
Interestingly, during labour, female person babies do have faster eye rates than boys.

2. Morning sickness that'southward not likewise bad
It has been suggested that meaning with male child symptoms include less vomiting because higher hormone levels in daughter babies crusade worse morn sickness. British medical journal The Lancet did publish ane written report to show that mothers with hyperemesis gravidarum (extreme morning sickness suffered by the likes of Princess Kate and Amy Schumer) are more than likely to accept girls.
But, equally you lot may remember, poor old Kate was affected by this condition for each of her iii pregnancies, and in the end the odds went the way of the boys, with two sons to ane daughter. So not a sure fire predictor then of babe's sexual practice. Besides, if it'due south your start child, how practice you know if the morn sickness is worse or not?

3. Lustrous hair and skin
When up the duff with a boy, the onetime wives tales say your skin is more likely to be pimple free (again, due to non having those pesky girl hormones alleged to crusade breakouts) and your hair thick and shiny (because of the benefits of male testosterone).
In reality, pregnancy plays whack with all your hormones and the difference between boy baby and girl babe hormones is non significant. It could get either way, or both – good and bad skin, total and limp hair - over the course of the nine months.
The Sun does study a French study that says "mums who suffer from acne while significant are ninety per cent more than probable to give birth to a daughter."
In an article on Carolina Parent, Dr Kelly Leggett weighs in on the pilus myth: "Your age will bear upon your hair texture more than your pregnancy."
"Normally, a woman loses about 100 hairs a solar day as office of hair growth's natural cycle," ob-gyn Dr Aviva Stein says in the same commodity. "During pregnancy, regardless of baby gender, the hormone estrogen prolongs the meaning adult female's hair-growth phase, resulting in less shedding of hair."

4. If information technology's all out forepart
Another long-believed story is that if the pregnancy weight gain is heavy on the hips and bum, information technology's a girl (due to that pesky estrogen again) only if the baby seems to only be a bump out front, then information technology is more likely to be a boy.
According to the BBC, this theory doesn't hold water, as the shape of the bump depends on the foetus'south position: "If information technology has its back alongside the mother's front end this makes her abdomen stick right out. If the baby's dorsum is parallel with the mother's back the result is that the belly looks flatter. And as the position the developing baby adopts is not dependent on its sexual activity, it is a myth that the shape indicates whether it is a male child or a girl."
Besides, putting on weight in the hips and bum is the natural storage for the actress diet a baby of either sexual activity needs."The rear end is exactly where we want a woman to put on weight," says Professor Kathleen Grand. Rasmussen. "Fat stored in that location is not visceral, it doesn't end upward in hard-to-break-downward adipose tissue the way it would in her abdomen, making it much easier to lose subsequently pregnancy."

5. A hankering for chips, not ice cream
At that place is a theory going around that if you crave salty, savoury foods, you lot are having a boy, and that if the drastic desire is for sweet stuff, it's more than likely to be a girl. Kinda like that whole "That's What Little Girls Are fabricated Of" rhyme, suggesting "Sugar and spice and all things nice" mean a girl.
Then what happens if you lot crave the old pregnancy favourite of pickles and ice-cream combo? Savoury and sweet?
"There's no scientific show to dorsum up any of these beliefs," Livestrong.com reports of the suggestion in an article all about cravings.
In fact, that petty critter inside y'all is but sucking up all your nutrients as it grows, so what you require is most likely what your torso is running out of, regardless of if it's a boy or a girl.

6. Big ambition
The old story that mums swallow more when carrying boys seems to be fact, with a US written report reporting that of 244 women tested, on average those with boys on board ate 10% more than those with girls.
In the British Medical Journal, Prof Dimitrios Trichopoulos writes: "Our findings back up the hypothesis that women carrying male person rather than female embryos may have college free energy requirements."
7. Keeping it on the down-low
The most pop belief about how you can tell what sex the baby volition exist is by looking at how you lot are conveying, with the theory that girls sit higher, and boys hang down the lesser.
Similar to the "where you gain weight" theory, there doesn't seem to be whatsoever good reason – or basis – for this erstwhile wives tale.
Professor Steve Robson, the Vice President of the Purple Australian and New Zealand College of Obstetricians and Gynaecologists, toldThe Huffington Post Commonwealth of australia, "It's clear to say that a child's genitals has zero to exercise with how the adult female's body looks when she is pregnant. The way a woman carries a baby has more to do with the size of the infant - and so the belly tends to pivot frontward."

eight. The nuptials ring spin
Tie your ring to a piece of cord and hold information technology in front of your belly. If it swings backwards and forwards, it'south a boy, just if it goes around in circles, it'southward a girl. (Though some sites say it's the other way effectually! So that but goes to show you how reliable this myth is.)
nine. A wee trick
Like the pH of your pool, you can test your pee. Adding Draino (drain cleaner) to your urine supposedly turns it green for a daughter and blue for a boy. What if information technology's aqua? In fact, the many sites suggesting this method tin can not agree what colour indicates what event.
Also, VeryWellFamily reports that information technology is extremely dangerous to mix these two substances as it tin can crusade fumes that are not at all good for you.
A safer manner suggested by Healthy Mummy is to add bicarb to your pee. If it fizzes, information technology's a boy.
Not truthful saysMedical News Today: "At that place is no proof that the sex of an unborn infant has whatsoever effect on the pH of a adult female's urine. Also, many other known factors can make a woman'southward urine more or less acidic."

10. Chinese birth chart
Hmmm. Apparently an ancient Chinese document just requires the Chinese age of the mother and the Chinese month of formulation to work out the sex of your child. You can try it here.
But every bit the mother of twins, one a boy and ane a girl, who I guess were conceived in the same calendar month and while I was the same historic period, this method would have a definite 50% failure rate for me.
11. The key to it all
A bit of a flaw with this method: you lot can't do this ane if you've read this. A key is placed in forepart of a pregnant adult female. If she picks it by the top, fatter bit, instead of by the long narrow bit, it'south a boy. This one definitely veers towards the story-of-an-elderly-married-adult female variety.

12. Skinny dads
There seems to be some merit to this 1, a Danish study showed that fathers who put on more weight during their partners pregnancy were more likely to accept girls.

thirteen. Best foot forward
The 15thcentury Distaff Gospels advises that those who walk with their right foot starting time are expecting a boy. Unsurprisingly, we tin't notice any research on this theory.

14. Mother'south Intuition
Guessing the sex activity of your child, you would expect to get information technology right 50% of the fourth dimension. But a New Scientist report has proved that maternal instinct - where the mum-to-be just has a gut feeling – is proved correct more often than not, with right guesses around 70% of the time.

xv. Over the counter gender tests
Available from the likes of Chemist Warehouse, these products are supposed to be able to tell yous the sex of your infant from 10 weeks.
The reviews are mixed. There does non seem to be any formal studies proving their accuracy and andthe Intelligender visitor'southward website "does non recommend making any financial, emotional or family planning decisions based on the test results. This includes painting a nursery!"

And now for some more than scientific methods:
16. Claret test
This can be done from almost nine weeks and takes about a week to get the results. The pathologists search a sample of your blood for the babe's DNA, which can also reveal the baby's sex. The purpose of this test is more unremarkably used to check for Down Syndrome and other genetic conditions, so y'all may need to pay.

17 and 18. CVS or Amniocentesis testing
Chorionic villus sampling (which tests some of the placenta) tin be done at xi to 13 weeks. Amnio (which tests the amniotic fluid) tin can be done from 16 to 20 weeks. While these invasive procedures can predict the sex of a child with 99% accuracy, they both acquit run a risk of miscarriage and so are not recommended except to rule out genetic conditions.
xix. Ultrasound
The most reliable style is to video the little bugger and meet if you can see what needs to be seen. But a discussion of warning, the kiddo may not co-operate by flashing and in rare cases it can exist interpreted incorrectly. Ultrasound is usually washed betwixt 18 and 26 weeks and is a routine part of pre-natal medical testing.
Dr John Williams from Cedars-Sinai tells CNN of ultrasounds, "if it's washed past a skilled person... there's 90% to 95% certainty on gender."

20. Nativity
When in doubt, await till it's out. That's a pretty definite issue one-way or the other. You accept a 50% chance each pregnancy of having a boy!

And every bit a bonus...
Here is one more way to tell: the intriguing nub theory.
