Eleven days after the AZ vaccine and I have bleeding. My last period was three years ago. I had discomfort and irritability the last couple of days that I didn’t even recognise as being the same as PMS, it’s been so long (and I am irritable at the best of times). I just hope it’s a one-off. As it is I have to go to my doc because I had minimal bleeding over a year ago and she’s being very cautious just in case it’s something nasty (last tests said all normal, though). Bloody pest, having this happen! At least I still have some reusable pads.
