I know this isn't the place to get medical advice but it's preferable to googling and I've always had very sound and sensible advice when I was on the pregnancy boards so here goes..!
I had my second vaccine of Pfizer on 21st July, since then I have had almost daily bouts of what I can only describe as morning sickness and dizziness/weakness. At first I didn't make the link, and when my clockwork period didn't appear on time, I panicked (have mirena coil) and I took a test, which was negative. It was only when I read about the link between the vaccine and periods that I have started to wonder whether the sickness is linked to the vaccine - has anyone else experienced similar? I'm starting to panic (perhaps irrationally) that it is something sinister, but I don't feel poorly enough to justify calling my GP. I'd really appreciate anyone who has thoughts/experiences/knowledge on the subject.
