Spotting for a week

Giselle

I’ve been spotting for a week now. at first it was a little heavy and dark brown. on day 3, i woke up and it was actual bright red blood so i put a tampon in. the tampon didn’t fill at all and it was just back yo dark brown. the next day, i was on the toilet and i had bright red blood again. and then a FAT flood clot. but then after that, nothing. back to brown. now, day 7, it’s just brown spotting, but it’s light (flow). i took a pregnancy test and it’s negative. we used condoms and pulled out.

is this hormone imbalance or bc i’m stressed? please help.
