I am 56 and went onto evorel conti a year ish ago having been period free for 6 months (I was on evorel sequi.) I was then period free for another 6 months until I had my covid jab, and I then had a period. Things settled again, no issue with second vaccine...but then had a period after the booster. I then had a period free month, but have had a period for the 2 months since. What is going on? Do I need to discuss with GP or can I assume this is vaccine related??
