AF was due 15/03/18 but started getting red spot on 14/03/18, and gradually became heavy AF and after 8 days it became light spotty again and till now am still getting some red spot when I clean after weeing😊in total I having been seeing red for 14days. I have done two pregnancy test a week apart and both came out negative. another fertile window stat today 28/03/18 according to Glow. Just wondering if anyone understand what's going on or if anyone is going through same. #babydust
