Period after depo


Have anyone dealt with weird periods after discontinuing depo? My last shot was November last year, I was due for a shot in Feb2016 and never went. Ever since the. My periods are getting longer and heavier. Started out with being 8 days and now I’m at 18-20 day of my period... for the first week it’s off and on. I’ll be on it for about an hour and not be on it again until the next day. It’s really heavy too. It’s kind of scary when I think about how heavy it is. Just wondering if anyone else has been going through this and if you have any suggestions. Doctor said it’s the new normal.
