It is very possible something call round ligament pain, which is when the muscles around the uterus begins to stretch as it grows. it is quite common and most women experience it to some degree or another. If you are really worried though, call your OB and have them check you out to ease your mind. That's what the doctor is there for. :) Good luck and congrats on the pregnancy!
Cramping at 9 weeks is very normal. I had all kinds of cramping and it scared the crap out of me. As long as your are not bleeding or having severe pain (like can't move or stand), you are fine. I am currently 22 weeks and have had 2 miscarriages and 1 ectopic in my past. I was told I would never make it out a the 1st trimester because I have PCOS and hypothyroid. Well here I am and my baby girl is completely healthy and all of my tests have come up normal. I will keep you and your baby in my prayers. You will be ok :)
I cramped all the time up until like 16 weeks. It was like a dull pain for short periods of time. I eventually got use to it...Im glad thats over with though. I think its just your body growing & changing.
