Should i be okay?

So I'm in a long distance relationship been on BC for a couple of months but since he left I never missed a pill but taken it really late like up to 4 hours then I got my period. Then this weekend he surprised me this. And we pulled out the first 2/times however the 3rd and 4th we didnt. And I was a little in easy since I usually get a sponge at a back up. And since I didn't take it at the same time and late the week before 2 hours later I got plan b just in case even tho the chances should be low right especially if it as the 3rd or fourth ? I kept taking the pill tho the regular time. And notice I've been really dry so I think it's working.
