Worrying 2 week, 40 tampon period?

I’ve been on my period for 2 full weeks, and have used around 40 tampons. Literally not an exaggeration. Used the last one from a brand new box of 34 this morning and have borrowed some others. Is this dangerous enough to call the doctor about? I always have really bad periods, they last 8 or 9 days and I bleed a helluva lot. But it’s never been like this. I started a new birth control a little while back but this is my 2nd period since starting it and 1st wasn’t like this. I have a history of a bad reproductive system (had 3 huge ovarian cysts removed and didn’t have a period for a couple of years which put me at risk for fallopian tube/ovarian cancer and uterine cancer since my uterine walls were so thick from lack of period). I’m also 16 years old so. Let me know if anyone needs any other info.
