36 weeks pregnant
Early term is next; GBS swab week
From 37 weeks the pregnancy is early term. This week many clinics collect a Group B streptococcus swab. The baby’s head may settle into the pelvis (lightening), or it may not.

Tips for this week
Attend the GBS test if offered. If you are GBS-positive, antibiotics in labor are the usual plan — not an automatic cesarean. Sleep on your side. Call if you cannot feel the usual movements after a rest and a cold drink, following your clinic’s method.
