gaining weight! some tmi - sorry!

mummy_gerdes

I lost nearly 2 stone with mfp before christmas - then had some time off during christmas. i started again afterwards but a bit half heartedley. then i really opushed myself to get back into it! and i did. BUT..i have been having quite alot of health problems knee and fatigue which has stopped me exercising. i am still eating with in my calories but i seem to be gaining weight rather than losing it! its so frustrating!!!!!!
when i mention fatigue it is not just oh i feel tired and cant be bothered it is exhaustion from the moment i wake up. that feeling you get when you are mentally and physically exhausted is how ive felt for the past 2 months - plus i ma getting dizzy spells and headaches on top of this. i have had full blood work done and it is all fine now waiting to see a neuro consultant.
any way as i am not up to streuous exercise - i try and walk a bit each day - why is my weight going up?!
i came off birth control at the end of feb as we are trying for a 2nd baby but surley that should make it go down. also havent had a TOM yet but feels like i am about to.
any advise greatly appreciated!!!
