Have you heard that COVID-19 might affect your menstrual cycle?
No, I’m not talking about COVID-19 vaccines.
I’m talking about COVID-19.
More specifically, the COVID-19 lockdowns.
Can COVID-19 Affect Your Menstrual Cycle?
Wait, how would the COVID-19 lockdowns affect your menstrual cycle?
“Seven-hundred and forty-nine participant responses were included for final analysis, over half of which cited a change in their menstrual cycle. Over one third of participants experienced a change in bleeding patterns (35.6%). Secondly, the study aimed to identify the main contributing factors to such changes in the menstrual cycle. The greatest contributing factor to reported changes was stress.”

While that idea that those who are recently vaccinated are shedding spike proteins and causing others to develop problems with their periods is ridiculous, whether or not someone who was recently vaccinated could themselves have menstrual irregularities is an open question.
“We have not heard of disruption of menstruation cycles following receipt of the COVID-19 vaccine, nor would there be a biological theory to explain why this would happen.”

What is not in question is that anti-vaccine folks are taking advantage of the issue to try and scare others away from getting vaccinated and protected.
