I couldn't find my birth control this morning(April 27th), so I obviously didn't take it. I couldn't find it when I got home either so I still haven't taken it. Not only did we have unprotected sex, but he finished inside me. I didn't go to the bathroom and

"expel" until about 10-15 minutes afterwards. My stomach has been hurting. I don't wanna say cramping because it's not like period cramping. Just twinges of very light cramps and just feeling sick. Kinda feel a tad nauseous with a headache too. According to the app I have on my iPhone, my last day of fertility was the 24th but last night I still had a little of the clear gooey ovulation discharge. We usually don't finish inside but when we have I didn't feel like this.
My questions are as follows:
1) Is it heard of to have a stomach ache from being finished in?
2) Does missing just one pill really make all the difference?
3) Can you get pregnant right after ovulating? I know sperm can live for 5 days but I'm not well versed in the live span of ovum
4) I've read people online saying that they just kinda "felt it" or "just knew" from the moment of conception. Have any of you ever experienced that?
5) Should I continue to take my birth control(If I can freakin' find it that is)? I don't wanna possibly harm the baby if I am
My next period is due May 7th. If I still feel funky around then or happen to be late, I'll test and I'll keep y'all updated.
