PLEASE RESPOND ASAP

There is a chance (a very small one) that I am pregnant. I think I started my period 5 days early, but since I'm on birth control, I can't tell if I'm just slotting or if I'm actually on my period, and my normal pills are just effecting my blood flow, bc I'm cramping like crazy.

Is it okay to skip to sugar pills so I can know if I am actually in my period or not? I'm very scared and anxious to make sure that I am not pregnant.
