Concerned 😟

Chelsea
I have been taking a pill form of birth control for two months now. It's called Aubra. It was approved by my doctor. I was just concerned because I have been experiencing really bad abdominal pain today, not like normal cramps...and my period this month (that started Wednesday) was SUPER light. Normally my first days are super heavy, and I was thinking it was just the birth control kicking in...but now with this pain, almost concerned I could be pregnant?...should I take a test or just go see a doctor? :/
