Wibu to track my dd periods? I had an interfering mum without boundaries - read my my diaries, opened my post and so on - so i am wary of encroaching in this way She did not start until age 15. The first real period was ok, she cried a little, said mum i feel gross and I dont know what to do. The next day she woke up a bit like a teenage bear with a sore head, incredibly angry and saying she hates me. Obviously ive been supportive and not reacted, as it clear as day to me it is hormones altering her mood. When she seemed better, I gently pointed this out to her and she took it on board. I would like to make a note in my phone of when she comes on, so i can tie up her potential mood swings with the cycle, and then I wont be worrying about other things and can reassure myself. Wibu?
