Had intercourse on last day of period-on 19th may and had fresh read blood bleeding during it. Felt pelvic pain during sex. The condom got stuck in me for 30 mins and I douched with water to finally take it out if my vagina. Later on, I am seeing light red vaginal discharge which does not require any sanitary pad from my vagina for past 10 days. I have never had this type of vaginal bleeding between menstrual cycles. I do not have any pelvic pain/ cramps. I saw a doctor-suggested taking sysron n twice daily for 20 days along with doxycycline twice daily for 10 days. My bloody discharge has stopped within 2 days of starting meds but my doctor said if I discontinue the meds the bleeding will start again. The doctor also asked me to do transvaginal ultrasound and tsh blood. Did pregnancy tests thrice- all negative. Next period is due on 17th july. My periods are 7 days long, not painful, more or less regular. Do I need tvs? Why bloody discharge happened? After completing sysron n 20 days course can I stop?
