I used the Nuvaring for 3 weeks while waiting for a tubal ligation. I am a single mom with 4 kids and was loving life until I used that ring. Two weeks after insertion, I was crying about everything and tired. I felt like I was 2 months pregnant except MUCH more emotional. The third week I was snapping at my kids and fighting with my boyfriend. 24 hours after taking it out, I felt like a new person. I will not use the Nuvaring again.
