Girls hi ? Who was prescribed Utrozhestan, is there any effect from it? I'm worried about my child's health and mine... I have tachycardia on the background of taking it, they said I need to endure, as it was prescribed due to shortening of the cervix... I've been drinking for 2 months and will continue until 37 weeks... And even more, I am interested in who has already given birth and passed some period, did it not affect their health?
