Is it normal to have colostrum at 3 weeks pregnancy?

Yes, it can be normal to have colostrum at three weeks of pregnancy, although it is more commonly noted later in pregnancy. Colostrum is the first milk produced by the breasts, and hormonal changes during early pregnancy may lead to its production. However, experiencing colostrum this early is not typical for everyone, and if there are concerns, it's best to consult a healthcare provider.
