I'm the same way

Lucky for me, now that I'm in my second trimester, my depression isn't as prounounced as it always was. I don't think that's going to last though, as I've been crying for the past two days about every little thing. I'm so scared I'm going to get post-partum depression.
What anti-depressant did he prescribe if you don't mind my asking? My doc said there wasn't much he could do, but I keep hearing about there being medications that can be taken while pregnant and I'm considering getting a second opinion.
