So on may 18 i had AF (do have irregular periods so im not always ure when i will ovulate or get my next period) and maybe a week ot two weeks after that my bf and i had sex. On june 14 in the morning after i pee i wipe and had light brown spotting then that night i went to the bathroom and had bright red bleeding not like my usual but i did put a pad to sleep the next morning june 15 went to the bathroom and the pad had a long streak that was brown almost black never had that happen to me before and when i wiped again i had brown spotting. The spotting stopped until afternoon again i saw spotting but it was light brown with very faint pink this then stopped again after maybe an hour on june 16 i saw only one spot on my panty liner and when i wiped there was no more spotting and i havent had any spotting or bleeding since then. I havent had any pregnancy symptoms at all but I decided to take a HPT june 18 in the mornin and it was negative. Could this have been implantation bleeding, or just my mind playing games, or did i take the test too early?
