I had my booster on Sunday (pfizer, same as my vaccine and had no side effects whatsoever with first 2 jabs) but yesterday, I went for a wee and there was blood when I wiped (sorry if that’s tmi) but it wasn’t like a proper period, and before the end of the day, it had faded away. I’m on the depo injection and haven’t had a period for years. However, I am due my next injection next week, so could have been spotting because I was due my next one. Just a bit of a coincidence, maybe.
But I was feeling very shivery and unwell for a couple of hours during the day.
