3 Months of Bleeding

I've been bleeding for 3 months, my doctor tells me it's normal and I'll be fine but I had an RN, MA, and another Doctor tell me I need to ditch that doctor because she's telling me wrong. I've also been told I could possibly be anemic which makes total sense as I've been so tired and weak and I always feel jittery which I'm assuming is from low BP. I just want more opinions or to know if anyone else has experienced this and turned out fine.
