Ok so I had unprotected sex on October 5 , and he did cum inside of me , I took a plan b within 15 hours but on my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> it said that I ovulated that day also and we had sex around like 2-3 am in the morning . A day after it hurted for me to pee I went to the doctor to get tested and they said chlamydia and I goi treated for it the next day I took the pills my pain when urinating went away . They gave me the 500 mg pill azithmycin and I have been feeling nauseous every since cramps loose stool kinda diarrhea but I’m also constipated . I have cramps and every once in a while my back HURTS ALL OVER . And I’m suppose to come on either tonight or tomorrow I took a pregnancy test 8 days after me having sex and it said negative so should I take another one I also have sharp pains in my breasts sometimes . No spotting or anything
