Anyone have diarrhea

I'm a few days past my peak day and had sex on that day and since yesterday I have had severe diarrhea, to the point my bottom and muscles hurt, I have had it 6 times in 2 days, I have never had it this bad after ovulation, anyone have this after and became pregnant? Btw this is the first time I have caught my peak day and had sex. Hoping this is the time.
