I was out of the country last month and didn't have access to the new nuvaring, so I was 2 days late for inserting a new ring (inserted 2 days going into my 5th week). Then I have been spotting all month this month. Today has been the third day into 4th week on this month's schedule and I'm still not getting a real period but spotting blood. I am a lot more moody this week and the sense of smell definitely got heightened. My boyfriend ejaculated inside of me once this month and I am now worried that I might be pregnant. I thought as long as I have the nuvaring in for 7 days, the ring should be preventing pregnancy for 99%. How late should I get a period after I take the ring out? Should I be concerned?
