5 months after giving birth, every day before taking a hot bath or when it is windy and cold, I get goose bumps and my hands and feet are cold and shivery. It happens less when it is hot. I have a slight fever and feel hot all over. Some days I wear a jacket all day, and at night I have to wear a jacket at midnight.

My last period was on July 27, 2021. On August 11, 2021, I got the first Covid vaccination (Astrazeneca). But when my period was on August 27, 2021, I did not have my period and until now, September 8, 2021, I still have not had it. Previously, my period was quite regular, if there was a difference, it was only a few days. I bought a test kit and I was not pregnant, and my last gynecological examination on July 19, 2021 was normal. So, doctor, can you tell me if my late period is a side effect of the Covid vaccination? Thank you!
