I think what she did is fab!
Just over half the population deals with periods. They are not always easy to manage. Often painful. Usually with other symptoms. I get migraines around my period and I cannot for the life of me do a think until it passes. even the pain killers leave me feeling woozy and off colour.
Raising awareness of the impact they have on our lives for the other 50% who really have no idea at all is a great thing. Every single one of us will have a story or a time where our periods halted our day to day lives.
For me I get the migraines and cramps that can be so bad the pain goes through my thighs and I cannot walk. We all know how hard it is to get time off work to manage it and I'm not saying everyone needs time off (you lucky buggers!) for a percentage of us open discussion like this, raising a little bit more awareness and understanding is a good thing.
To finish I am ridiculously open with my OH about periods, cramps, pain etc I even tweet about it to my (mostly) male followers and you know what, Some of them even respond because they didn't realise for some women it can be so tough. The only comparisons they have are their GFs and even then many women don't talk about it and hide it away like the 'curse' it has been labelled as :(
