How do I know the ring is in the right way?

First, if all of the ring is in your vagina it’s effective as birth control. Generally, the most comfortable place is tucked up against the side of your vaginal wall. To get it there, push it up as far as you can get it inside the vagina with your finger. It’s funny to say, but the ring almost has a sixth sense for getting itself into the right place. If you insert the ring and can’t feel it, you’ve got it in correctly.
