Whether you aren’t able to find out the gender of your baby, or have decided to keep it as a surprise, looking out for signs you are having a boy or girl can be a fun and exciting way to pass the time while you wait for the exciting discovery.
Some women believe having extreme morning sickness means you should paint your nursery blue, while others swear that it’s all about ‘the angle of the dangle’ on your scan images. While we can’t guarantee that any of these theories carry solid scientific weight, we can bring you the most well-known theories, comments from the real mums on our forums, and the expert opinion from the Harley Street Fertility Clinic’s Dr Geetha Venkat. Happy guessing!
Well-known old wives’ tales
- One theory suggests you tie a ring to some thread, hang it over your stomach and if it swings from side to side it’s a boy, if it moves round in circles you are having a girl.
- if you are carrying your bump low down and all ‘out in front’ you are said to be having a boy, if your bump is high and ‘spread out’ you could be expecting a girl.
- Some people believe that you can tell using a simple sum to predict gender; add your age to the number of the month you conceived in, if the number is odd, it’s a girl, if it’s even, a boy.
- A well known theory suggests if you are craving sweet foods you are expecting a baby girl, if you fancy a savoury snack, it’s a boy.
- Some mothers believe that the speed of your baby’s heartbeat holds the key: over 140bpm and you're having a girl, under and it is a boy.
Real mums share their theories
“My mum thinks the way you can tell is by where your bump lies. If it’s really low down by your pubic area: boy, high up under your boobs: girl. She has two daughters and said we were high up, and she was convinced I was having a boy because he was so low and always has been. Turns out she was right!” gsmummy55
“They say if you crave sweet things (as I did) you’ll be having a girl, and I am. but don’t really know anything else!” Mummy_Gracie
“I read that boy sperm swim faster but don't last as long and girl sperm are a bit slow but hang around for days. So you're right that if you know when you ovulate you may be able to predict the sex. But if you had sex three days before and on the day then it could be either a girl (still hanging around) or a boy (swimming fast)” diggys_mum
“I've found it follows family. I know I’m having a little boy because my mum had really bad morning sickness with both me and my younger sister, but none with my brother. I had no morning sickness or nausea at all (Lucky me!) and my 20 week scan confirmed it! I’ve found it generally follows in a family pattern so ask any sisters” mummytobe6.11.12
The expert opinion
Dr Geetha Venkat, Director of Harley Street Fertility Clinic says,
“There are some Old Wives' tales I come across more than others. One particular tale which proves very popular is that depending on the shape and position of a woman’s baby bump, the sex of the baby can be identified. Put simply, there is no medical evidence to support this.
"The other popular myth which has received a large amount of interest recently is if a woman is experiencing severe morning sickness, they will have a girl. And there is some reasoning behind this. Hormones can make women very poorly and if your baby is a girl, there will be an increased level of oestrogen within your body, which can often lead to sickness. That being said, we have seen many women suffering from this problem who have gone on to have boys, so again, this is not a definitive identification tool.
"The most efficient and definite way of telling the sex of your baby is to go for a scan during the 14thand 15th weeks of your pregnancy. If you try to discover this too early, you may need to redecorate the nursery."
