I'm perimenopausal and every time I get my period, the hormones seem to create havoc with my eating habits - more than they ever have actually. I literally cannot even face cooking normal healthy food that I eat every other week of the month- like stir frys etc. I made a veggie spaghetti Bol earlier with vegetables and quorn and it made me heave when I came to eat it myself 
. It's something I regularly eat normally.
All I want to eat during my period is really plain food like cereal and toast. Weirdly I was exactly the same when I was pregnant both times. I've always been a bit of a hormonal eater but it's literally gone up another level!!
Aibu to think it must be hormones? Perimenopause seems like some new level of bonkers things.
