With my first, I started feeling sick around week 7, I don't think I actually GOT sick until about 8 or 9 weeks. It lasted my entire pregnancy.. no joke. I was also on zofran and it was a lifesaver! I didn't have a pill that dissolved so I had to swallow it but if I took it immediately, it usually stayed down. There were plenty of days that it came back up though.
This time, I am not feeling sick everyday, but it's still there. Yesterday, was my first day that I had to run to the toilet and gag (which I hate so much worse than actually vomiting). For some reason, I don't think it's going to be as bad this go around.
