I had sex four days ago we used protection during intercourse but not foreplay, he didnt finish inside me but he may have dripped inside me during foreplay. I was also at my peak point of ovulation. I stopped taking birth control two months ago due to my hormones being all over and was in process of getting another contraceptive method put in place. How many days past ovulation can i test for pregnancy if i know i was ovulating on the day i had sex.
