Period problem. Be pragnent right?

Doctors , last month I had unprotected sex , he didn't ejaculate in me because i am so careful I keep an eye on it, then still to be safe I took unwanted 72 pill after 20- 30 mins. After 1 day I'm still freaking out as I heard girls do get pragnent without ejaculation . So, I took the more expensive pill iPill . Then my period was 5 days early with no cramps. !! I usually have my period on 21st every month. But last month ( November) was on 15th. So this month December, I was hoping for 15th it didn't came , out of stress and craziness freaking me out I took unwanted 72 again on 19st. This month ( stupid ,I know). Now is 23rd I still don't get my period. I am having cramp just now . Till now, no pregnancy symptoms. I tried visiting a gynecologist I book appointment and she was not there. So sadly I waste my money and went back home . Now I'm cramping. Is it possible to miss period if I take more than 1 contraceptive pill ? I can't be pragnent right ? I wanna suicide now. My stress lev
