Have posted about this on another similar thread but coming back to this original one.

I got back to my GP like people suggested and got bloodwork done, my haemoglobin is under half what it should be - on the day I had my blood taken and went out for dinner, went for one drink afterwards with my husband and just about fell asleep in the bar which I felt lousy about (this was 8pm!). It kind of crept up on me but looking back I can see how abnormal my fatigue was.

I have high dose iron tablets now and hopeful I will be back to normal in a few months.
