Hi msgirl,
I'm on zoloft currently and we're TTC #2 - I've had chat's with my GP and while there are some small risks, overall the side effects are rare and I'm confident everything will be ok (my dose is low and I know that my health is a vital part of the TTC process). As Kirsty_lee said, zoloft is one of the safest to take during pregnancy, but if you have any concerns visit your GP or health professional and have a chat, I'm sure they can put your mind at ease if you're still worried

I agree with HannahD - whatever is best for you will absolutely be best for your baby. Goodluck with your TTC journey!
