What do we know about the COVID-19 vaccine and menstrual cycles?

Healthcare workers answer questions about the COVID-19 vaccines.

Yolanda Tinajero, MD, OB/GYN explains that many things may affect someone’s menstrual cycle from time to time but that the COVID-19 vaccines shouldn’t impact a person’s ability to become pregnant in the future.

There have been some anecdotal reports about patients stating that they’ve seen changes in their menstrual cycle after receiving the COVID vaccine. So, what I remind patients is that there are a lot of other things that can affect someone’s menstrual cycle and that can include changes with sleep, the stress that one experiences. Um, so for that reason, I try to reassure them their cycles can be a little bit different from time to time, but that doesn’t necessarily impact their ability to become pregnant in the future.
