As someone who was trying to conceive while the vaccine rolled out, this isn’t surprising. People were regularly reporting basal temperature spikes, delayed ovulation, and delayed periods. This is a community that is extremely data-oriented, since with the right measurements you’re able to predict your fertile (or non-fertile) window.
I was disappointed to see how little research there was into menstruation at the time. We were told that the vaccine was perfectly safe, and even questioning the vaccine made you ‘anti-vax.’ Now over a full year later the scientific community is confirming what random message boards have been saying all along. It may be safe, but nobody really cared to look at the impact on menstruation or pregnancy beyond confirming that the rate of miscarriage is unchanged.
