Im on 50mg zoloft every morning. Before going on it i got opinions from my ob, a perinatal specialist and a pediatrician. All agreed it was in mine and babys best intrest. I started on it at 15wks, i am 36+ now and will continue to take it after birth and while breastfeeding.
I was on Zoloft before I got pregnant but many of my doctors told me to quit taking it before I tried due to it not being good during pregnancy.
Zoloft may have been suggested because it's an older one and there is more data. Although, no medication is totally safe during pregnancy the benefits may outweigh the risk. I take welbutrin sr 150 mg once a day and I'm 17 weeks with twins. It's noted as a safer one since it's one of the oldest antidepressants on the market. It's a personal decision do your research and trust your gut.
