I just found this blog by doing a search because I’m having the same issues and I kind of wondered if it didn’t have anything to do with my vaccination in April. I got the Johnson and Johnson vaccine. My last official period was October 2018. I did have one period June of 2020 but was told that was only because I started synthetic hormones one month prior. No periods since. I’m 50. I could always tell when I ovulated and about five days ago I almost guarantee I was ovulating. Haven’t felt that in a few years. And then three days ago my nipples have gotten very sore and very sensitive. I’m not concerned but putting this out there in case there is a correlation with the vaccines. I’m not planning to see my gynecologist until October. Unless something gets worse. Just interested to hear what others are experiencing.
