Mostly from the j&j one, one women i saw said within hours her period came 8 days early. another women said she was taking birth control and the covid vax made her period come almost immediately after nothing for 9 months, and they say it sticks around for about 2 weeks. any idea what this could mean or what it's doing to the body? is it forcefully killing the eggs and therefore forcing the body to get rid of them?
