Newbie here.
I have come off the nexplanon in June
Last two cycles every 28 days then 27 days for 7 days getting back to normal. According to flow app my ovulation day was 11th September. Spotting and cramps on the 12,13,15 and 16th September. I'm due to start my period on the 26th of September i took a pregnancy test on the 20th September and what I think is a positive. But I took another one this morning and its negative. Can It be a chemical?? Thanks everyone
