Oh, the "what ifs" are the worst. :grouphug:
I can tell you, that I know of women who have taken Zoloft during their pregnancies with no ill effects. It was one of the reasons I agreed to try Zoloft instead of some other SSRI.
And I have seen an improvement in my digestive issues (probably because I am not soaking my organs in adrenaline all the time {blush!!} my doc had said that some people have issues, and with my IBS-D she was somewhat concerned about that, but it has not been an issue (and I was sure it was going to be, of course....)
Zoloft didn't make me drowsy at all (Xanax did when I started that - it took about a week before I stopped needing an afternoon nap - but I am now on 2mg a day (spread over the day) and it doesn't make me sleepy at all (and I can take an extra if I am in a particularly stressful situation.)
