TTC Low iron?

Been TTC 2 years. My SO has been tested he’s been fine. I have always had low iron as I have tried to give blood before and been rejected or dr have told me due to other blood tests. I’m being referred to gynaecologist to test my fertility as my bloods came back normal, however before they can do that, I have been prescribed 3 months worth of ferrous fumarate before they can refer me to gynaecologist.

Has anyone else been on these? And has anyone else had their fertility effected by low iron? The dr said they probably won’t help me but I am feeling hopeful!!

Any stories welcome :)
