You know what cheyenne?
I had exactly the same thing except mine was about 3 days after my period was due, and id already found out I was pregnant!
I havent seen my ante natal clinic yet because they didnt make my appointment til this week when i'll be 16 weeks but I can tell you now I didnt have a miscarriage!
Theres defionately something in there making it difficult for me to roll over at night!! :p
maybe you should go and talk to your doctor about it!
