I’m directing this question to all women, not just cisgender ones or ones that menstruate. My understanding is that we all can experience hormonal fluctuations during the month, for some it’s just more predictable or obvious than others. Hormone therapy can have this effect too for our trans sisters. Curious what you notice, if anything.
It’s all by symptoms. In my case it was night sweats, sweaty palms so bad I had to give up my hobbies, sudden development of eczema, dead libido, inability to climax, brain fog, loss of speech fluency, morning sickness, and the occasional very mild hot flash when angry or stressed.
There’s not really any test for peri, because hormone labs only take a snapshot of one moment. Not very useful because hormones fluctuate day to day. If doctors brush you off (super common ugh are we even people) there are telehealth sites that can help.
