i'm about 5-6 weeks along with my first and i know where your coming from!! i've been getting period-like cramps for about three weeks now and i've been a nervous wreck. last night i ended up curled up in the foetal position on my bed almost in tears cause of the pain and because i was so scared.
i spoke to the doctor about it this arvo and she said, not to worry, it's just your body stretching and loosening up for the growth of your bub.
i know the pains are scary but just curl up until it's comfy and just wait it out, thats all i can say to do.
