The weight gain begins.
Boy, girl — or a big surprise? There are pros and cons of each side. A word of caution: If you want to keep your baby's sex a secret, let your provider and the ultrasound technician know right away so they don't inadvertently blurt it out in the middle of an ultrasound exam or while reviewing your test results. Under certain circumstances (for example, if you're older than 35 or if your screening tests indicate a potential issue), your doctor may discuss amniocentesis with you.
Amniocentesis is a test usually done between 15 and 18 weeks that can detect abnormalities in a fetus, such as Down syndrome. During this test, a very thin needle is inserted into the amniotic fluid surrounding the baby in the uterus and a sample of the fluid is taken and analysed. Amniocentesis does carry a very slight risk of miscarriage, so talk to your doctor about your concerns and the risks and advantages of the test.

Although you still can’t feel your baby’s movements he is more active and has become more controlled and fluid, making the most of the space he has to move around. He is growing a soft covering of downy hairs called lanugo which will cover his whole body; this will be replaced by fat later in the pregnancy and will fall out prior to delivery. Your baby’s genitals are now fully developed. His little body is now making red blood cells and thyroid hormones as well as meconium (waste).
