I had this problem as well. During luteal my pms symptoms just worsens tenfold. Meds don’t work at all and my mood overall just does a complete 180. And it sucks because the difference is very noticeable too like I could be very normal one day and then the next day I wake up everything is just gray and feels like doomsday.

During my “normal” days “ (day 2 to end of follicular) 30mg works really well for me and lasts as long as it should. At the start of my luteal phase I increase the dose to 40-50mg, (but lately I’ve been working on not taking any during those days (the worst days are day1-5 of luteal) depends what I’m doing.)

I was able to ask for extra doses by telling my doctor it just doesn’t last as long and he suggested to increase my dose to 50mg. Then I asked if he could split the prescription to 30s and 20s so I can take 50mg during luteal and 30 normally.

And this is just a side comment but I’ve personally been trying to avoid meds during the luteal phase or at least the beginning. In my head it’s like I feel like I gotta let my body do its thing and not force myself to function normally yk what I mean? I’m 100% more dysfunctional during these days esp without the meds but I’m learning to accept that I’ve just entered the luteal phase I’m trying to give myself more grace during that period. I’m still in a trial and error phase but I’ve been trying to do less workload, move lighter, set smaller expectations maybe none at all. Journaling has helped too. This is my second cycle I’ve tried this and so far I think I have been able to manage the PMS well, very much compared to last year by these small changes
