What should i do???

Bl

Okay so today makes 105 days straight non-stop having my period. My doctor's keep telling me it's normal, my OBGYN, didn't do an examination, or anything. She simply told me it's normal, especially with the Depo shot. I don't think bleeding this long is normal. It's not spotting. It's like having a normal cycle non-stop. All the OBGYN wants to do it put me on MORE BIRTH CONTROL! like no, I've had only one shot which was in October. My period stopped for 24 days, and started on November 12th, and has not stopped since. I'm kinda lost with what I should do... I really need help
