Hello, I would be happy to help you with your question.
Just as when there is variation in taking the pill, removing the nuvaring
intermittently can lead to breakthrough bleeding
. Part of the advantage of the nuvaring is that it can stay in place during intercourse, and when left in place it is associated with less breakthrough bleeding. Also, given your inconsistent use of the nuvaring, it is possible that pregnancy
might occur, though probably unlikely. Nonetheless, you need to check a pregnancy now and again in 2 weeks at the very least.
I hope that this helps and good luck!
