Your pregnancy at 13 weeks

Your baby at 13 weeks

Your baby weighs around 25g. Your baby’s ovaries or testes are fully developed inside their body, and the genitals are forming outside their body. Where there was a swelling between the legs, there will now be a penis or clitoris growing, although you will not usually be able to find out the sex of your baby at an ultrasound scan at this stage.

You at 13 weeks

If you’ve been feeling sick and tired with morning sickness, you’ll probably start to feel better when you’re around 13 or 14 weeks pregnant. Some women start to experience an increased sex drive around this time, possibly as a result of pregnancy hormones or increased blood flow to the pelvic area. Some women do not, and this is perfectly normal. You’ll notice a small bump developing as your womb grows and moves upwards. If you’ve been feeling the urge to pee more often over the last few months, it’s because your womb was pressing on your bladder. This should ease off now. See your doctor if you notice any pain when you pee. Urinary tract infections can happen in pregnancy, and it’s important to treat them quickly to reduce the risk of kidney infection.
