Period pain after booster jab

[Kitty337]

Anyone else experienced this?had my booster yesterday afternoon and started cramping (mild but still annoying!) early this morning.

I have. Longer cycle & both periods since I’ve been more crampy. Same with the first jab and I was back to normal for third cycle

I had my first period after the booster ten days early. I felt like absolute death for most of the month after it too.

This is so annoying. I still dont get why that vaccine is linked to our cycles- i really hope it doesn't mess up fertility!

Vaccines trigger our immune system and periods are also linked to our immune systems.

During ovulation our immune system is suppressed, as it wants to fight off foreign invaders (ie sperm).
The vaccine increases our immune system and therefore has triggered periods/period like symptoms in women.
