Please help!!

Hey, this is my first post on here. My period has been going on for 10+ days. I’m calling my doctor in the AM but wanted to check her, too. I’m 21 and have been on birth control (Nikki) for two years with no side effects. I also had heavy cramping at the beginning of this period which I don’t normally have. Also wanting to know if you think I’ll have to have a pelvic exam done. 😬 Thank you in advance! Also not sexually active.
