I had unprotected sex on the 5th day of October the app said that that was my ovulation day , I took a plan b within 15 hours . The next day it hurted to pee bad and blood was in my urine I went to Thur doctor and got tested and they said I had chlamydia I got treatment for it 500 mg azithmycin pills , 1 day treatment. ok I was fine , I took a pregnancy test on the 13th It said negative. But now I’m late by 2 days of my period and my breast are sore and my back is killing me . I took another pregnancy test a day before my period is supposed to start and it said negative. So , why am I feeling like this if my tests are negative . I am very moody and irritated. Maybe it’s because I’m stressed I don’t want to be pregnant
