Diarrhea and progesterone

[Ansumpasty]

Hello,
I've noticed a pattern with my IBS in that around 7-8 days before my period, I get diarrhoea. I had a look at the hormones of the menstual cycle and this is when progesterone is at its highest.
Most things online say that progesterone causes constipation, not diarrhoea. There is a clear pattern emerging with me though and I was wondering if there was anyone educated in this field or with IBS and similar problems who can reassure me or explain why this might happen?
I'm a massive worrier, which doesn't help :)
Thanks!

I get this despite everything saying I shouldn't. Not sure it helps, but you're not alone!

Thanks, Justasec!
Even one person having similar makes me feel better as I was starting to think I was some kind of anomaly! Thanks :)

I have the same! Although my understanding is that it's to do with falling hormone levels at that time of the month; either way, there is evidence to show the menstrual cycle affects IBS, so don't worry, you're not the only one!

I get this and lots of bad ibs symptoms in both the week before my period and just before ovulation. It’s very common apparently, hormones affect people in different ways and some are more sensitive to them than others

Thank you
