Ok, so I wear my nuvaring continuous, meaning, I wear it for a full 28 days and then toss it and immediately replace it with a new one for the next 28 day cycle, so I don't have periods. I was supposed to change my ring on dec 29th, well, I forgot to set an alarm and didn't. It was still in, but past the 28 day cycle, I realized it this morning, Jan 2nd, 4 days past due. Husband and I had sex last night, he always finishes inside me bc I'm on the ring. It was still in, but again, past due. What are the chances that I am going to be pregnant ? I haven't put the new one in yet bc I don't want to in case I end up being pregnant. Should I put it in? If not, when should I? How much is this going to mess my cycle up?
