Congratulations your baby is growing so fast as he is over 16 inches long and is heading into a growth spurt.
He can now turn can turn his head from side to side, and his arms, legs, and body are starting to plump up as needed fat accumulates underneath his skin.
Your baby is probably moving a lot, too, so you may have trouble sleeping because your baby's kicks and somersaults keep you up. All this moving is a sign that your baby is active and healthy.
You will also notice that the muscles in your uterus tighten from time to time. A lot of women feel these random contractions known as Braxton Hicks contractions – in the second half of pregnancy. Often lasting about 30 seconds, they're irregular, and at this point, they should be infrequent and painless.
You need to call your doctor when you have frequent contractions, even those that don't hurt because it may be a sign of preterm labour. Call your doctor as soon as possible if you have more than four contractions in an hour or any other signs of preterm labour.
Signs of preterm labour include an increase in vaginal discharge or a change in the type of discharge (if it becomes watery, bloody or mucus-like, – even if it's pink or just tinged with blood); an increase in pressure in the pelvic area, abdominal pain or menstrual-like cramping;; or low back pain, especially if you didn't have it before.
You may have noticed some leaking of colostrum, or "premilk," from your breasts lately. If so, then you can try tucking some nursing pads into your bra to protect your clothes and if not, you don’t need to worry yourself because your breasts are making colostrum even if you don't see any.)
If your current bra is too tight, you might also want to pick up a nursing bra. Choose a nursing bra at least one cup size bigger than you need now. You will definitely need it when your milk comes in.
If it’s a boy you are having, you and your partner will want to take some time to think about whether or not to have your baby circumcised. Find out from your doctor the pros and cons, and what the procedure involves.
