Scared 😟

So on the first of this month I had protected sex maybe two weeks later I start the patch form of birth control and to my understanding I’m supposed to put the patch on every Sunday for 24hrs but skip the week of my cycle this last Sunday I messed up and put on a patch my period was supposed to come on today and its not on yet my period is usually spot on every time and it should have been in by now also my boobs usually hurt up until my period starts but this time it didn’t I’m experiencing some heavy cramping I don’t know if I’m freaking my self out or not but could I still be pregnant? Maybe a little cum over flowed out the condom is that possible?please help ladies 🙁
