It's just sad to see someone suffer needlessly, Overrun, b/c the GP just can't be bothered.
One of my best friends had heavy bleeding like that that turned out to be from fibroids. As she didn't want any more kids, she had a simple procedure called endometrial ablation. She had it as an outpatient and her quality of life is way, way better now, it's like she got her life back.
Honestly, my energy levels were SO much better after I had DD2 and got over the anaemia, I felt like the Energiser bunny.
You'll be amazed at the difference in mood and energy levels when you kick the anaemia.
