Hello girls! At 27 weeks they told me that my weight doesn't match the due date, I was taking Elevit prenatal and iron. Now everything is fine, on the 32nd week, it develops according to schedule. But the gynecologist didn't prescribe anything to take ? What did you take at this stage of pregnancy with normal course of pregnancy? Maybe again a complex? My gynecologist doesn't care ??‍♀️
