Methyldopa cause postnatal depression?

Anyone heard or experience postnatal depression from taking methyldopa due to high bp? I developed high bp at 34 weeks and was prescribed with methyldopa, it was with hold immediately after delivery. However, my bp shoot up again to 150/104 2 days after delivery and yesterday (1 week post delivery) I went back for review, gyne ask to continue methyldopa 2 times a day 🤔 So I'm rather confuse now.
