Pregnancy risk here?

Eden
I'm currently on the pill and I am very diligent about taking it. I never have missed a pill.  
This is the first month my boyfriend and I haven't regularly used condoms. He had not once finished inside me - however, he has orgasmed then we waited about 30 minutes then had sex again. 
I'm scheduled for my period Tuesday and I'm worried. Should I be worried about a pregnancy risk?
