"i changed from yaz to the nuvaring as i liked the idea of it being a lower dose of hormones. i found it very easy to use but had to stop it after 2 weeks. not only did i suffer from a uti but the nuvaring made me extremely tired so much so it started to ruin my life i went from being fit and active to spending every chance i got sleeping as soon as i took the ring out within 24 hours my energy levels were back to normal."
