Hi there, I started taking ferrous fumarate on the 13th November (on doctor's advice) because my serum ferritin had become very low, as it tends to do without supplementation. I started getting every other day B12 injections on the 21st November for the first time, at my GP surgery. My period was due that day, and I'm usually really very regular, but it's still not arrived, although it keeps seeming like it's going to. I'm just wondering if this could have anything to do with the new vitamins? I would have expected the opposite to be honest!
I am 44, so it's possible that it could be a perimenopause thing, but it just seems terribly coincidental timing. As always, any advice appreciated
