Might be TMI

okayyy.. so in need of some advice, so last month, my period was a couple days late, so I took a test, was negative then my period came the next day, so comes this month, period is so far 6 days late, don’t wanna take a test cause I’m pretty sure it’s negative (no we don’t use protection, yes I know I can get pregnant of pre cum) anywho, so today is day 6 no signs of AF at all or pregnancy symptoms, so today I went to the bathroom and pooped and I saw blood, (not in my poop) so I’m like okay I probably just got my period, I wipped my vagina and yes, there was blood so I plugged the tunnel up, so about 2 hours later I go to change my tampon and there’s brown blood but barley any, so I didn’t put anything in and now ther s no blood at all. Do I take a test?? Am I getting my period? My family and I went out to dinner and I have the “shits” now and I’m super nacious change in body temp and idk what’s going on ugh
