Bedding in pains or something more serious?

Rebecca
I found out I was pregnant nearly away ago, 6 tests later all positive.... Just to make sure as was stunned as it was our first month of trying and it didn't seem to go to plan at the time, I'm now experiencing cramping like pains a lot of the time, is it just baby bedding in and uterus expanding or should i be worried that it could be a early miscarriage, feeling very anxious about it
