So i miscarried at 17 weeks on March 3rd (we think an incompetent cervix) and i stopped bleeding 1 week later. i tested negative by March 10 and had no more pregnancy symptoms. we started having sex almost every day for the last two weeks and my period would have normally started back up around the 1st but no period or spotting . ive been testing and getting negatives until today. ive only been reading the test after 60 seconds and throwing it away but this time i waited another minute or two and i think i see a line. is this my rainbow baby or evap line or negative ????
