Plan b, should I be in the clear ?

Unfortunetly I have stopped taking birth control a month ago, which has been the most dumbest decision ever. I stopped taking it because I was not planning on being active again 
I know that this should not be a form of birth control but I have taken it 3 times total this month. Better to be safe then sorry 
The 1st was after we had unprotected sex during the end of my period
The 2nd time was after my fertile days the condom ripped but we both continued 
The third was that following week, and the condom got stuck inside me 
I have been throwing up everything I eat or drink since the 21st before I took my other plan b, i get nauseous anytime I try to eat but at the same time I wana eat everything in sight. I've slept literally like a bear
