OK, so I am two-three weeks late. I had a bit of spotting when I wiped a couple days before my period was due. However, nothing on pants liner like normal when I spot. I took a couple at home pregnancy tests which all were negative, except one which I thought I may have seen a faint line. I also took a blood test 3 days after my period was due, and it came back negative as well. If I were to have gotten pregnant it would have been March 14 or 15. The last time I tested was the negative blood test on April 1! Any advice?
