I am currently 3 days late, and no sign of it coming, usually after intercourse it would come but nothing,but I went to the doctors yesterday took a pregnancy a test and it was negative, I was told that for best results a should Wait a week.. I dont want to get my hopes up, because in the past I have had irregular periods, but ever since I removed the IUD in April my period has been on point....don't know what to think or do...
