I'd talk to your doctor about it. From the sounds of it your body does not react well to this type of hormonal birth control and I imagine this is going right along with that. I know ever since I've been on the ring my period starts about 3 days after I take it out and lasts about 4 days. That's after I take it out, though, so I don't know how to gauge your situation since you were already bleeding. So conclusion: go see a doctor.

I got on the ring about 16 days ago on the 1st day of my prd and my prd still hasnt gone away. I have no idea what going on

How heavy is the bleeding?

when starting a new BC, it may cause you to have a long period / different type of period for 1-3 months and then your body should adjust. The problem of why you are still bleeding is because when you take birth control for a week and then all of a sudden stop, you will get your perios pretty soon after that. So, you are probably having 2 periods one directly after the other due to you taking the ring out. I had the same problem, i was on nuvaring and my period lasted ten days. my doctor said it takes tiem to adjust. give it a chance.

I am having the same problem, I am now on my third month of using the ring and this time my period came early (before taking the ring out)and I am still bleeding (day last time it was 9 days! I hope it evens out soon!
