I had bad m/s till about 8 weeks, then felt great for next couple of weeks. And literatlly, it happened overnight. I felt better then i did before i was preg, my bbs wernt sore anymore or anything. And i had also had bleeding, so i was abit panicky. I really really wanted to go to the doctor, and tell them i had more bleeding, to get them to do another test, but, i held out. And everything was fine. Then it hit me again coming into the 2nd trim - i think lasted till about 16 - 17 weeks.
