There is a reasonable chance that you are pregnant. The first few days of the cycle determine whether or not you are going to ovulate, so the first week of the cycle is the most important time to use your contraceptive.
Because your period was October 22, I would expect ovulation about 14 days later or November 3rd ish. A the earliest that a pregnancy test would be positive would be about 10 days later or November 14th. Many tests would not be positive for another 4-5 days, so if negative, I would repeat.
Your Nuva ring will not hurt the baby if you are pregnant, but of course it should be removed in the event of a positive test.
Thank you for your answer! It was very helpful.
Is gooey looking white discharge a symptom that I would have ovulated, then?
