This is an edit of the Period Hack combining multiple versions with my own tuning to create the latest, ultimate version, V3 if you like. Overall, this version makes periods less intrusive and more manageable than before.

This all started from the Period Hack mod by Smonaff on Mod The Sims. This mod brings a touch of real life to teen and adult female sims as they will now have periods. When a sim is on their period, their hygiene and comfort need will suffer more than usual, and they will experience PMS symptoms; cramps, munchies, and gas. They will need to change their hygiene product, a tampon by default, every 4 hours which simply pushes them to use the toilet regardless of their bladder need.

What many people don't realize though, is that smonaff actually released a V2 of this mod in the comments section on post 440. This update introduced many in-game tuning options so you could fine-tune how periods work in your game to your own taste. These settings allow you to control the amount of notifications the mod produces, whether townies and NPCs will get periods too (separate option for each, I like having it on for townies but off for NPCs), whether undead sims will get periods (makes most sense to have this off) and also allows you to change the eligibility age to children instead of teens.
Meduza then built on this V2, improving the undead toggle so that servos/robots are recognized as undead, as well as the custom playable ghosts and skelebros. Therefore, these non-human sims will not get periods if the undead toggle is off.
Something that had always bothered me about the period mod so far was that the 'Period...' menu option was always present on every female sim you clicked on, cluttering up the pie menu. When I saw that Meduza had experience editing this mod, I asked her how I could limit the menu option to only show when the active sim is clicking on themselves, rather than when any sim is clicking on any female sim. Meduza kindly made this edit for me.
This mod includes the above 4 iterations, plus my own tuning which, in my opinion, makes periods less annoying and intrusive. Firstly, periods used to last 8-16 hours, but I changed it so they last 23-24 hours for every sim. But that sounds like it makes them more annoying?! you might ask...well no, because periods used to happen every 4 days, but I've changed them to be every 7 days. So now, sims will have a period for one full day once per week. I think this makes them much easier to manage and keep track of. Furthermore, periods used to really tank the sims' hygiene and comfort need, especially hygiene, but I've significantly reduced this. The hygiene used to decay a whopping 15x faster during a period and now its just 2x faster than normal. See the before and after pictures below, Angela's needs after almost 5 hours with my mod (I forgot to pause after 4 lol) are much better than they were after 4 hours with the original.

I tried to increase the duration of the tampons/sanitary products since there is a tuning option for it, but turns out this is unused and its hard set in the BHAV. Perhaps I'll look into it again one day but every 4 hours isn't too annoying.
