SOS HELP

I had sex with my SO about two weeks ago. We didn't use a condom for the first few minutes but then I made him put one on. I missed my pill that day. This past Sunday we had sex again with protection but the condom broke. I missed a pill Monday. 
I've been so stressed out about finals and life keeps getting in the way and it's freaking me out. The pill I missed Monday is halfway through the last week of active pills. Should I skip the placebo week and keep taking active pills because I missed a pill in the last week after having sex? Or should I take the pills as normal and pray for my period? 
Also I understand that this month I've been extremely irresponsible and careless and it very well could bite me in the ass. I'm already freaking out so please no negative "you shouldn't be having sex" comments. After this month though I'm really considering not having sex anymore. These two times are the first two times we've had sex in 7 months because of personal issue so I very well might just take sex out of the equation again. 
Anyways if anyone has any advice that would be amazing.
