So I am 13 days late. I've never been more than a day late ever. my husband and I have been through Fertility issues with low sperm counts for a few years. 6 months ago we finally decided not to do any treatments for personal reasons. now I'm late! I took a pregnancy test yesterday (12 days late) but it was negative. I also had some very minor cramping throughout the day yesterday but still no period! anyone else have experience like this?
