I had unprotected sex on the 9th day of putting in the nuvaring (never tried bc before, and I inserted it in between periods) and now I am supposed to take it out in 3 days, but I started to feel my normal period symptoms 3 days ago (this is around the time I should be getting my period), as well as nausea today (usually never feel nauseated). I have used it as directed, but is it possible that I am pregnant? Can you tell this early? (1 week and 2 days after having the unprotected sex)
