"I stopped using Nuvaring in December 2019.. I bought an ovulation test but it's positive every other day?"

It is possible that the ovulation test you purchased is defective or expired, causing it to show a positive result every other day. It is important to ensure you are following the instructions correctly and that you purchased the test from a reliable source. If you suspect the test may be faulty, consider returning it to the place of purchase for verification or try using a different brand of ovulation test.
