Vaccine and periods?

[squiddybear]

Hi, I had my first vaccine 2 weeks ago (Pfizer). I was due on Wednesday this week and so far nothing has arrived! I've taken a pregnancy test just in case and it is negative.

I wouldn't say I was a clockwork person and my cycle has always been between 36 and 40 days (ever since my periods started). Could this be a cause of the vaccine? Am I just overthinking.

I was supposed to ovulate around the time the vaccine was given but actually started much later...

I'm a little worried (I'm a worrier!)

Has anyone experienced the same?

Hi Ladies, did your periods come back. I had the jab on the 28th March and still no sign. I'm getting concerned as its not like me. 1000% not pregnant (not had sex for 9 yrs).
