2 vaccines: flu and pertussis; oral glucose tolerance test and group b strep swab. Other tests perhaps depending on the pregnant women's health condition. Visit gynae after week 7, they will arrange for tests etc as you progress
Scans are monthly, towards end of tri 3 is 1-2 weeks once. I only took 1 jab for whooping cough. 3 blood tests for gestational diabetes test. 8 weeks to detect heartbeat, 20W is the only detailed scan. That’s all.
