SWITCHING BIRTH CONTROL PROBLEMS

Hailey
So I switched birth control 2 weeks ago to a lower estrogen because I was getting so sick. Well now I'm and getting these bumps that look like big bits but there not... they itch and hurt. Switching my birth control is the only thing I have changed lately. No new soaps, lotions, or detergents. Should I go back to the doctor or wait? Sorry for the weird photos.
