Talk to Gynecologist on Gynaecology

I have been facing vaginal irritation and soreness since a month. My doctor tested me for infection which was negative. I was prescribed Dermocrat ointment which makes it better and now I am off it. I had also been taking Omatril for 21 days as I was facing vaginal bleeding from an ovarian cyst. I just finished my course two days back. Last night I had intercourse after which I noticed spotting. I thought my periods have started which should after stopping Omatril but then after a few hours the spotting stopped. Now I’mj confused if it was due to intercourse or what. Also I feel a lil pain during sex but last night it was mild
