Creamy white discharge during sex

I’m on birth control pills. 2 months ago I skipped the placebo pills to miss my period.Last month I missed my period even though I took the pills. I am sexually active but he always pulls out plus the pill and I took a pregnancy test and wasn’t pregnant. This month i’m on day one of the placebo pill and I still never got my period and I had white creamy discharge during sex. Has this happened to anyone? Does anyone know what this means?
