So I’ve been on birth control for two years and I had some complications with my pharmacy so basically I was without for a month. Now that I’m back on it my body is trying to readjust

I’ve been bleeding for a whole month basically only one week in March was when I wasn’t. I got off my period with the regular red blood but after that none of the symptoms have subsided I’m still exhausted and I still have back pain and very very moody and hungry all the time but now it’s deep red blood it’s basically brown. I’ve also been bleeding though everything too. Is it normal to be bleeding this much for this long?
