I started using nuvaring for the first time on October 16, but I started having foul odor which I detected it could be a form of infection so I removed the ring October 28. Automatically, I started my period October the 31th and I had unprotected sex with my husband the November 3rd while still doing my period. It is 28 days from my last period could I be pregnant?

It is possible, but unlikely unless you were to ovulate early. I would wait a bit longer and see if your period is just off from ending your use of the nuvaring. If no period after another week or so, try a pregnancy test.

Thank you, I really appreciate the response
