Idk what’s going on with me..

Lately I’ve been feeling breast soreness and cramping as if I’m going to get my period but thing is... I’m in birth control and my period are super regular so I don’t expect me period for another two weeks. Yet I’m feeling intense cramping not often but when I do it’s bad. I also have diarrhea. Last time I had sex was about a week and a half ago and just yesterday I missed my first pill :( I noticed today when I was going to take my regular pill and saw that I had skipped over yesterday’s. What I did is I took both at once. Idk what’s going on but I’m not feeling so good. Im not feeling pregnant... if that’s a thing... but I don’t feel nauseous or anything of the sort. I’m kinda scared but not? Idk anyone explain?
