So this morning I had some pink and brown blood and I thought I was starting my period because I'm 16 days late. I went to the doctors to get a pee test and I went to pee in the cup and a bunch of blood came out so I thought it was my period. I put in a tampon and just told the doctor I started. Then I woke up from a nap, went to change my tampon and there was no blood and still none. I took a test Saturday and it was negative, but idk. I'm no longer bleeding and I only bleed for 8 hours. I need help so I know what to do!!
