I missed my bc pill then took it the next morning and the one for that day about two hours late. I know for a fact my partner ejaculated inside me the night I took the late one. We were quite drunk. Anyway, I missed 2 days after hoping I would come on like I usually do if I miss a pill. Usually I begin atleast spotting as soon as I miss....I didn't. It is day 3 and I've been having back pain and stomach cramps the past couple days. And today I feel nauseous. Am I pregnant? Also, I take zovia 1/35.
