2 day bleeding

Branna

Serious question. I was late Monday and i came on my period for 2 days . Came off and the third which was Halloween i didn’t need a pad but i put one under just in case some blood but not a lot. . Haven’t seen blood since. A week and half later I started spotting Brown first then pink a little then back to brown then bright red then back to brown. . This Wednesday it stopped. All this happened & I was ovulating and I still am. It’s watery and slimy. I took a test after the 2 day period. Then took another one when i was spotting it said negative. My next period isn’t until the end of this month ? What am I ? Should I take another test or not ? Is it just because I’m drinking water i started spotting. I had sex like 3 or 4 days before Halloween, and another time before that. I don’t know if it died or what ? Because i seen bright red idk. Please help.
