Thanks for sharing.
I had my first dose of AZ on the 16th March. Normal period a couple of weeks later, normal period earlier this month (starting 5th May), and I appear to now be having another period, which started yesterday. I don't know if it is related to the vaccine, as I figured not as i have had normal periods since, but 🤷🏻♀️ Interesting that the article briefly mentions steroid injections as I had one of those for the first time 16th April, again normal period after that, but then this, so maybe it could be that affecting it (I've been trying to find I for of a link but hadn't come across much, so it's interesting that it's mentioned there).
