He pulled out but I accidentally got some inside me?

He pulled out and I went to wipe it off with my hand (tmi) because it was on my back/butt and then forgot about it and wiped the outside of my vagina and I'm sure some of it got inside me. I am on birth control but I never take it at the same time so I'm kinda worried I could be pregnant. If I am should I wait until my inactive pills start to take a test or just skip the inactive pills completely to see if I get implantation bleeding
