So I'm on progesterone after having a cerclage due to short cervix. I have to take it twice a day. I don't know if its the progesterone but since I've been taking them I've been angry literally everyday and depressive mood, very low indeed to the point of having invasive thoughts. Anyone else experienced this? Obviously I have to be on them until 34 weeks but I'm worried that it will cause postnatal or even prenatal depression in me.
