so my bf and i have sex regularly but we always wear the condom right & fitted correctly and pull out every single time. my period is always irregular. this exactly time last year i was late by 13 days and this month i was late by 7 days. usually, on the first day of my period, i get bad cramps and heavy bleeding. i had frequent urination for like 2 days and then this month, on the first day, i had brown blood on the pad and when i wipe it would be red. i put on a new pad before bed and when i woke up it was completely clean. the second day however, i had a heavier flow almost filling up a whole pad. still completely brown, but when i wiped it was red. i put on a new pad before bed and clean again. third day (today), there was barely anything but there was brown blood and when i wipe it is pink.

everyday there was brown discharge like substances. im confused if this is implantation or a really weird period. my periods are usually short (5 days max) if that helps. i just dont think its possible if he hasnt came inside me but the symptoms kind of match up with early signs of pregnancy. thank u in advance.
