I was currently taking the nuva ring continuous to avoid my heavy cycles for the month of June and July. My menstruals usually came at the beginning of the month. Now I decided to go off it to take a break. I received one in Aug near the 26th lasting 6 days then Sept 23 lasting the same. I have unprotected sex the day after it ended but He didn't ejaculate inside of me. It's now the 22 of Oct and I'm worried. 2 pregnancy tests negative. Should I be worried?
