Chances?

So I just did stuff with my boyfriend. This is the first time we got sexual since we first started dating. We did not have sex but he fingered me. Then i gave him a hand Job. He cummed but not on me but on my hand and on himself too. It got on the best but we cleaned it up and it was on my arm and then I felt in on my thigh but no where near my vagina. I am worried there is a chance. I know there probably is not but I haven’t done anything since February so this is just scary especially because I was rapped. I’m just worried because I am not on birth control and my period is supposed to come in 4 Days. I need some relief.
