Hi, I had protected sex about a week ago. I am on nuvaring, and this is my second month. I have been on 3 different types of birth control for a year, so I'm not new to birth control. We used a condom, and the condom did not break and there was no leakage, now, I have been having very frequent urination. I have been drinking a ton of water, but I am still very worried that I could be pregnant.
