Period late - vaccine, pregnancy or PCOS?

[orangejuicer]

Not sure where to post sorry but wondering if the wisdom of MN can help.

My period is late, about 2 weeks. My last one was at the end of March, a week after my first jab. Could the supposed vaccine delay happen after a period has been?

I have PCOS but my cycles are actually pretty regular at the moment so am not sure it's this.

I could be pregnant (though chance is low) but 2 tests this week (3 days apart) have been negative. When would I start to see a strong line if it was a positive test?

I don't know exact dates for any of this as I don't generally keep track. I'm not a simpleton (promise!).

Any ideas?

Period still not here, and it feels like I have endless PMS symptoms.

Does anybody know what this might be?

Have you had a Covid vaccine? I had Pfizer and my period was v later after my 2nd dose.

I had my 2nd Pfizer jab and I was 3 weeks late with my period.

Usually pretty regular

There's also a v long thread on the Covid board about delays on periods following the AZ vaccine.

Thanks - I knew there was a thread but couldn't find it.

Yep had 1 AZ jab with my period straight after. It's arrived today so that's my answer, thanks all.
