I've raised this question as well. Even if you have PCOS you have periods, they're just super erratic and there's no timing them. Becky has stated that she hasn't menstruated in a while, but that doesn't mean she never has. I can't imagine an adult woman, and let's say for argument's sake that she's NEVER menstruated, would mistake pee pads for period pads. I don't think they're even kept in the same area of the store. I think Hambert genuinely needs pee pads for the above reasons mentioned, she likely has a weak bladder because of all the weight it's subjected to so, much like pregnant women, she pisses herself a bit when she stands up or puts any force on her pelvic area.
