Acne all over my body. Good results.

I'm 24 and was having throat issues since December last week so I was on medicines since then. My menstrual cycle was normal in January. I had unprotected intercourse and took an ipill after which I got my periods again after a week my  last period ended. In February I didn't got my periods and since a week I've been feeling very hot body temperature. My body is very sensitive towards hot temperature and hot substances and I have oily skin still never experienced acne or pimple on my skin but right now I'm having alot of acne all over my body (even on my scalp), majorly on forehead. My face is filled with acne. I've tried applying Betnovate N, natural alovera gel, neem face packs, having curd and buttermilk. Still I can't find good results.
