disclaimer - not religious and this is lighthearted.
I don't have periods as badly as many women. I used to struggle a lot in my teens, they'd make me throw up at school and all sorts.
Then I discovered the depo injection and was on it for close on 10 years. No periods at all. Came off as I didn't really think I was the one who should be pumping hormones into my body, then when periods eventually came back, the mess and discomfort was just not something I wanted to deal with, so had one dose before Covid hit and been off it since.
I don't really get PMT, I don't get floods, I don't get javelin arse (any more) so I should count myself lucky really 
BUT I seem to spend my life worrying about my period. I'm either on, and wondering if I'm going to leak. I'm either at or near the end, and wondering whether it's safe to stay off the tampons or if I'll have a 'second wind' (periods now very unpredictable). I have a blissful few days a month when one has finished before the next one is due-ish (they're erratic and no regular cycle) so another week or so of stress worrying I'll be caught short when out and about.
I've just come on today. That's a cycle of 67 days. 67! It's not as good as you think, because I've spent most of that time remembering to shove tissue in my pants on the off chance I'll come on and remembering to pack tampons every single time I leave the house.
So I've decided 'God' is a raging misogynist. He wouldn't make a man bleed (randomly for me) unpredictably and erratically and messily and leave them on tenterhooks for the next one. Surely, in all his infinite wisdom, he could have come up with a better reproductive system??
