Currently I'm 12 days late for AF, she should have came on 6/27...I've been extremely tired this last week, (slept 12 hours straight one day) backache, dizzy, and a HEAVY creamy then watery CM (sometimes so heavy feels like AF has come, but no blood at all). I had a MC in Jan and ever since would spot 3 or so s as before I started. But this month..nothing at all. I've taken 3 home tests( clear blue, first response and a dollar store brand) all came back negative.. but my mom says that most the women in our family they dont work for .so my question is..how long would you wait to try another test or should I call and see doctor and get a blood test?....
