The hunger games 😁 please don't ignore!

My husband and I are ttc but because of work shifts haven't had sex that often, we did it on 29th December (after AF) then on the 3rd Jan. I'm at my most fertile week and am soooo hungry! Seriously nothing at all is touching the sides, today I ate sandwich and crisps for lunch, a roast for tea then some leftover curry, it wasn't a huge amount but bad enough and some popcorn as well. I'm not due AF for another 3 weeks and on the odd month I've felt hungry it's been the week before my period is due not this soon. Has anyone else experienced this? I don't feel different in other ways just seriously hungryΒ
