Back story: on birth control for 1.5 years and stopped BC in June. Been TTC ever since. Posted below is a pregnancy test I took last week with what looks to be a faint line. Used another test which was negative then started my period. I assumed it was a chemical with the faint line. My period was very light and lasted only 2 days, now I am not bleeding but (TMI) when I stick a finger inside of me there is a small amount of dark brown blood. Does this sound like a chemical pregnancy?
