My Boyfriend doesn't know if he came in me !!

So last night me and my boyfriend had sex. Im not on birth control (which im planning to get on soon) but of course he used a condom. So usually when we have sex, when he gets ready to cum he pulls out to check the condom then put it back in to finish. But last night the condom broke !! But he did pull out & cum was all over the blanket but he doesn't know if he came in me just a little so we're both worried. But also my eve tracker says im suppose to get on my period in 5 days & im not fertile right now. Should i be worried or am i fine ??
