Please hope I hardly post for it. Anyone!!!

I had to get a new perception for my BC pill but was out of town. I had my last period start on the 21st of June. Which is when my pack ended. With sugar pills. And now today I'm bleeding. About medium. Is this another period because of me not talking pills and it making it off track? Dark clots. It's dark almost like old blood but idk. I'm stressed out. I did get my prescription now but I haven't received. Insurance probs. Anything helps.
