I had cramping and a bit of bleeding at 6 weeks and 9 weeks. Had a scan at 9+3 and everything was fine. I had mild cramping quite a lot in the first trimester as everything implanted and started to stretch so i'm sure yours is the same
I had the same and had bleeding later on so have had a few scans already (I am now 11 weeks) and all is fine. They told me it was implantation pains at that stage and later on when I had them again they said it was my uterus stretching for the baby to be able to grow. I really wouldn't worry everyone I have spoken to had cramps at some stage early on, and guess what....we all panicked so its not just you. Congratulations xx
A couple days before I took a test I was at work and had sudden cramping, I was certain I was about to start my period! Anyway 2 days later I took a test and it turned out I was 5 weeks pregnant so yes it's completely normal!
