PCOS post cycle Nausea

Some backstory: Hi y’all I’m a 27yo and I think I have been dealing with PCOS since I first got my period but because it was bad they started me on the pill when I was 18. From 18 - 25yo I never had a period no matter what pill combination we tried. Eventually I was tired of how the pill made me feel and I got off of it. I have been off now for 2 years in the meantime I fought with several healthcare officials to take my symptoms seriously and after many appts and a whole lot of money I finally got my. Since then I have made a lot of changes to help support my body and my hormone health like cutting out any alcohol, cutting out caffeine, daily supplement cocktails, Ovastiol and spearmint tea, Brazil nuts, etc.

My question: Within the last year I have started to get severely ill at the end of some of my cycles. I may have two days of a normal period and then I start to develop sulfur burps and start with diarrhea and puking. I’m actually caught in that right now since 5/22. I haven’t been able to eat anything for the last 4 days and I can barely keep down water or anti nausea meds which most the time I don’t. I have tried to do some research and find answers, but doctors haven’t been helpful and my best guess right now is it is something to do with the prostaglandins hormone that my body releases in excess. Does anyone else have symptoms and sickness like this around their period?

I’ve been feeling pretty defeated about it lately and know that it will take so many appts, doctors telling me there’s no link to my PCOS, probably throwing another BC pill at me, and a ton of money to figure anything out. So I wanted to ask this community first to see if there is anyone else like me struggling.

If you made it this far thanks in advance for any help and for reading my novel!
