Anything that can hit the cervix can cause issues. There is a previous post here that has a lot of info: http://health.walgreens.com/posts/Womens-Health/friable-cervix/show/491890 Taking birth control seems to make it worse from what I've read.
Do you think wearing tampons affects the condition?
Thank you so much! You're the first person who's given me something to work with!
This sounds like something I've read about called "friable cervix". From what I understand the cells of your cervix are different or delicate and it can affect your cycle and can result in post-intercourse bleeding. It may be something worth looking into.
