ive been on zoloft since about august 2011 for ppd.
I would definitely talk to your doctor about it.
I am also on Zoloft.
I had pretty bad ppd with Owen and have been on and off anti-depressants ever since. I stopped taking the last one just before finding out I was pregnant, it wasn't working out very well- I couldn't sleep at night. That being said, I have definitely been down lately, and going through a separation is making it worse. I have been told by one doctor that I can and maybe should start an anti-depressant, but another two that I should wait until baby is born. That makes it tough. I am going to try to get through the second trimester without anything, but consider introducing something in the third trimester, the thought of having ppd again, being single with 2 kids, terrifies me.
