I had cramps a couple days before I got my BFP, but then for about 2 weeks I just felt normal and started worrying about lack of symptoms..... I started having shocking m/s from about 5 and a half - 6 weeks, which lasted a number of weeks. Everything is ok so far. Youve still got plenty of time to get m/s, but of course, I wouldnt wish that upon you for this pregnancy!
