Neverending period, Please help!

Janay
My periods became weirdly longer than usual back in May (2014). Normally, I'd be on for like 10/11 days but all of a sudden I started being on for like 3 weeks, off for 1 week, then would be right back on. Went to the Dr in August and she told me I was stressed and come back in 6 months... I came on a week before Halloween and almost 5 days into the new year I'm still on. My flow varies anywhere from spotting to heavy. Tried to get a second opinion but neither my GYN or any of the other offices I've called can see me til mid/end of February. Has anyone else ever experienced this? Oh BTW, I am not on any type of BC and haven't been on any in almost 4 years (not interested in using it neither)
