You're welcome,

Remember stress can increase cortisol levels, and too much cortisol wrecks metabolisms...meaning increased weight, poor sleep, systemic inflammation and more. Additionally stress can also alter menstruation and bring about depression. 

Also, I'm curious how the covid vaccine is altering menstrual cycles…(e.g. heavy flow, longer periods, sore breasts, [which is an indication of too much estradiol] etc.)

Abstract

Research question: Does SARS-CoV-2 infection have an effect on ovarian reserve, sex hormones and menstruation of women of child-bearing age?

Design: This is a retrospective, cross-sectional study in which clinical and laboratory data from 237 women of child-bearing age diagnosed with COVID-19 were retrospectively reviewed. Menstrual data from 177 patients were analysed. Blood samples from the early follicular phase were tested for sex hormones and anti-Müllerian hormone (AMH).

Results: Among 237 patients with confirmed COVID-19, severely ill patients had more comorbidities than mildly ill patients (34% versus 8%), particularly for patients with diabetes, hepatic disease and malignant tumours. Of 177 patients with menstrual records, 45 (25%) patients presented with menstrual volume changes, and 50 (28%) patients had menstrual cycle changes, mainly a decreased volume (20%) and a prolonged cycle (19%). The average sex hormone and AMH concentrations of women of child-bearing age with COVID-19 were not different from those of age-matched controls.

You're awfully right about the stress thing.... hate to admit it but I've beeen hella stressed this week... thanks SNS I guess I'll have to make a dopamine fasting this week... and start with meditation

I was wondering the same about the vaccine and menstrual cycle since I recived my second dose and I was in my period, but truth to be told i haven't experience significant changes... maybe a little increase in volume... but it could be due better nutition... my period has always been super irregular and tends to look more like spotting than period, specially when in diet sometimes even leads to amenhorrea... but yeah basicaly very light period quite long (about a week or so... 10 days is my max) very short cycle (2weeks) or overextended cycle (more than 35 days) this time my cycle was 17 days (I hate it when is such a short cycle)
