Experience with Zoloft or other meds

I’ve had horrible anxiety and a history of perinatal depression with my first. Recently I’ve felt the feelings of overwhelming sadness, disconnect from baby, anxiety, stress, irritability, etc start to pop up again. I have tried alternative methods like therapy and stress management but I can’t workout because of SPD and recently moved to a new area where I can’t see a therapist until after birth. My OB has mentioned I could try low dose medications like Zoloft or other through that end of my pregnancy and have it peak after birth to help avoid PPA and PPD like I had with my first.

I’m worried about the side effects like more weight gain, baby having withdrawals, potential for bleeding out at birth (already anemic).

Has anyone had any behavioral meds during pregnancy or previous pregnancies? What was your experience?
