Yeah I had that- if I got up too quickly too it really hurt. It was period like pains for me and I had sharp pains on the side I ovulated from too, I had an early scan which reassured me because I found the pains quite scary too.Thanks both, 4/5 weeks so very early. I've spoken to my GP and they're monitoring hcg levels at the moment, just looking for other peoples experiences. It does feel like my period is going to come and any time i cough or sneeze it's sharp pain.
