Heh. My personal friends circle only, NOT scientific, but when I complained that they were aching - pretty much all of my cis female friends winced and said they remembered those days. ๐ I think some cis girls must get the hormone fluctuations and steep spikes, too, based on how moody a lot of teenage girls get...
As for how to help with the pain, I recommend a sports bra or other soft supportive bra. Advil also helped for me personally; don't know why, I am not a doctor, please don't consider this medical advice, but it did take the edge off.
