I CAN’T STOP BLEEDING! HELP PLS😭

So I got the bar last year in April. My main issue, (other than major out of control mood swings😡) is I legit cannot stop bleeding. It’s not heavy enough to wear a pad or a tampon therefore I wear liners. Sometimes on the occasion I stop for like 2-3 weeks if I’m lucky but then will continue for months and months after😑. At one point my doctor put me on the pill alongside it to regulate the bleeding but I couldn’t continue it as it was bad for my health 😭😭

I’m not too fussed about bleeding as I know the bar is very good at reducing the risk of pregnancy. We still use a condom every time even though I’m on birth control as I’m only 17 yrs old and cannot take any chances. Is bleeding all the time unhealthy and if so should I get on the pill?
