Discharge

I’ve been having this discharge on and off like I woke up and there was a ton. But after I wipe it there isn’t a lot. I had so irritation down there but go it check out a week ago and I was negative for all test. She told me to put Monistat on and just used mild soaps, no tight clothing and cotton underwear etc. the irritation went away instantly it felt and I had sex and he finished in me 3 times last week. I have that same irritation it it’s went away and now this discharge. I’m on the pill and i dont know if it’s because I’m ovulating? But I’m on the pill and I’m supposed to get my period next weeks so I’m not sure if the app is off ?
