Hormones & The Model

I was wondering what role hormones play when we focus on the model and on how our Ts create our Fs.
For example PMS or post partum: Do the hormones mess with our thoughts? Or do they create a certain physical sensation (as a C) that we than interpret in a way that causes our sadness/upset/anger/etc.
Given the number of women that so go through intense mood swings during their periods, pregnancy, or post partum, I would assume that there is something to it and I would love to understand how to place this with regards to the model.
Thank you in advance!
