@Howaboutthisone, I had very similar issues with constant heavy flooding/ bleeding for almost a year (no tablets stopped it). It became so bad that I couldn't leave the house.
Was fobbed off a lot. Similar to others "this is normal for many women, you'll just have to live with it!"
Eventually had hysteroscopy, they took a biopsy from suspected fibroid and laproscopic surgery to explore what else was wrong/causing it, as I had a lot of pain too.
Turns out I had a really bad case of endometriosis and had a lot of lesions in my abdomen which they lasered away whilst I was under GA.
They also put a mirena in saying it would solve all my problems.
It didn't.
I still bled almost every day (although, granted, not so heavily).
After almost 3 years of bleeding 23 days or so out of every month with only a day off here and there (not even all at once!), I asked them to remove it and they refused.
Took a further 8 months of pushing and white lies on my part to get it removed (end up lying and telling them I wanted to have another baby and implied that the consultant had agreed to me getting it removed).
Then went on to triptorelin which induces the menopause. Within 2 weeks of heavy bleeding, bleeding stopped completely and has stayed away for the first time in years. It's a monthly injection, and got side effects from 2nd month onwards (really bad hot flushes and night sweats). Gave me HRT to help stop these, which it did, but I've had to stop taking it after 5 months as it sent my blood pressure sky high (185/110) .
It's a very rare side effect, but since stopping it my BP is back to normal so it seems pretty conclusive that it was this medication causing it.
I haven't started bleeding again yet, but don't know what will happen in the longer term.
I'd be very careful having the mirena fitted as they really don't seem to like removing it even though it wasn't doing what it was meant to.
Keep pushing for a faster appointment, and don't let them keep fobbing you off. Good luck
