Ok so how fed up am i??

I have been having heavy long periods for years now and been put on mefamanic acid that i needed to take from varying days in my cycle that have never worked.

The last 4 months i have had 7 periods so decided to see the doc again.
He prescribed Norethisterone which i have now been taking for 19 days, i was supposed to take these from day 21 of my cycle but started bleeding on day 19 so began taking them on the first day of bleeding.

They have done nothing at all, so had another appointment with the G.P, who upped the amount to 4 tablets daily and added tranamexic acid into the mix.
this slowed the blood flow a little, but today day 19 of bleeding i`m flooding again.

I had blood tests last week that have returned normal meaning i aint staring the menopause early, and also found that i wasnt anaemic, how i will never know!

This is now seriously impacting on my life, with missed days at work, and generally having no energy at all..

Any ideas?? i realy could use some advice as i have not been diagnosed with anything, and today feel like asking for a total hysterectomy just to get shut of the bleeding.
