ADVICE PLEASE LADIES

Alright ladies so I missed my cycle from November 24th 2017-March 8th 2018. of course I thought I was pregnant but I wasn't.

Once I started my "cycle" I expected it to be as long as the ones I've had every month since I was 9 (which is always less than 7 days) but that was not the case!!! I have not stopped bleeding yet! Doctors are not taking me seriously because I'm not bleeding an incredible amount an hour. it's just like a period except it's heading on 3 MONTHS LONG. I have never used birth control, never had a miscarriage. Ladies please give me some advise!!!!
