So I had sex with out protection but then took plan b the next day a think two to three days after I bleed for about two 4 days heavily and red blood then I took two pregnancy test cuz I've take plan b before but I didn't bleed I took both pregnancy test on different days they both came out negative then I was late for my period but it finally came on the 4th day I believe very very heavy the first day and then way lighter the next day but not spotting and it continues to fluctuate like that for the rest of my period which lasted 10 days which is 3 days longer then my normal but it never was light bleeding and it had signs of a being a period like clots and stuff and it was red blood but it was such a strange period and I'm just confused. I'm also having pebbal poop which I'm vegan so it's strange i can't remember if that started before or after? Help??
