Anxiety medication

Alli
So I have been on medication for many years for anxiety disorder and obsessive compulsive disorder. About 2 years ago my little brother passed away and I was unfortunately there with him alone and it was incredibly traumatic. I was then additionally diagnosed with post traumatic stress disorder. I was already on Lexipro and then was added a ton of additional meds. When I decided to ttc, I weened off everything, which didn't go well. I became very depressed and my anxiety was through the roof. So I decided I needed to go back on something. My Gyn prescribed Zoloft. I'm on a low dose but I'm still nervous about side effects during pregnancy. Anyone have any advice or experience with taking meds while pregnant?
