Went to the doctors about my awful headaches today and was told it was stress and hormones

which I think I kind of knew anyway, but just felt like I needed a second opinion. Was good to be checked over so thoroughly and reassuring to know everything's OK, but I feel so rubbish today and so tired I can't concentrate. Just been sick and want to eat some food but I don't fancy anything apart from macdonalds! Isn't this how its supposed to be in the first tri rather than the second tri?! I'm too ashamed to bring macdonalds into work!
