I am two days away from test date after a natural fet, all week I have had period type cramps. Last night the pains were so bad it woke me up and I couldn't move. After 10 minutes the pain went as if they were never there. After all this I still have no period, which is good. I am getting really worried though. I never made it this close to transfer last time and my period is due. I am just curious to know if anyone has had pains but still go on to have a positive test.
