I think I messed up, y'all.....

I started taking bc about 2 months ago, this being my third pack. I took the first pack like I should have, period came when it should have, etc. I completely botched the second pack, and got my period super early while I was still taking a couple active pills. That period lasted about 13 days, resulting in me not taking an active pill for about 10 or 11 days, then missing my 4th pill in the first week of my new pack, and having unprotected sex that same day I missed. Should I be concerned about pregnancy or am I working myself up for no reason?
