DD is 12 and hasn't started her periods yet, although I suspect that might change very soon. She's had a few months of being a bit wobbly for a couple of days, but this week she has been a mess of hormones, sobbing, shouting, falling out with friends, barely able to hold a conversation without taking something to heart -the full works. She's said herself she's hormonal and she hates it.
Is it normally worse the first few months, or are we in for the long haul?
Is there any benefit in looking at her diet to try to improve things? Are supplements any good? I took evening primrose oil when I had bad PMT but I'm not sure it's a good idea for a 12yo?
