Anyone gotten pregnant on the patch?

So started the patch 3 months ago I have gotten two periods and last week was my free week and never got my period. Today I put my patch back on. Been getting headaches and feeling nauseous but I think the nauseous has to do with the headache. I've been consistent with the patch and have maybe gone one day over for replacing which shouldn't be a big deal but was wondering if anyone has gotten pregnant while on the birth control patch . I'll probably buy a pregnancy test today just to make sure I'm just laying down right now trying to feel better
