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.
