S.P.
You're past the three month mark. Ususally, it stops by then. I wouldn't worry. My sister is pg too and she has a couple of good days, then some bad. It's not unusual for it to stop and start or just end. My first pregnacy went like that. One day I was sick and the next I wasn't. I'm not going to tell you not to worry, you will anyway. Good luck and congradulations.
