Just wondering what your usual practice is.
I don't for the first 24 - 48 hours as usually too tired after waking with period pain/getting up to empty mooncup etc and feeling tired and weak/achey but have heard exercise during period can make you feel better.
I do exercise during last few days and it does make me feel better. Not wearing white shorts and rollerblading down hills 'woo argh Bodyform' style though.
