Breakthrough Bleeding?

🌸🦋
Hello, 
It was my first time on BC, and so i stopped my BC midpack (only 1 day before the end of the 2nd week of the pack). 
Had unprotected sex the day after I last took the BCP. Four days after stopping the BC, I had breakthrough bleeding from missing so much pills and when I had the breakthrough bleeding, there was a lot of EWCM that day (March 7th). After that, I had unprotected sex for 3 days in a row (9th 10th and 11th). 
I havent had a period since the btb and I've been cramping mildly. Usually when I cramp, my period comes the next day but it's been 4 days since I was supposed to expect my period if my cycle was still regular from before I got on the BC. I didn't take the last 2 weeks of the pill so I didnt get any bleeding like expected for the placebo week.  What do I do ?
