Help!!

I'm usually on oral contraceptives but in order to get my natural cycle back on track with my pills I decided to wait a month to take them again. I've been off of them for just over a week now, my tracker says I'm ovulating and have a 22% chance of pregnancy. Tonight I had a whoops moment and gave my boyfriend a blowjob and then he fingered me and I'm not 100% certain there was nothing on his hand when he did. It's really not in my plan to have a baby right now but I don't have access to the Plan B Pill. Any advice?
