Hello, I started using the Nuvaring as birth control about 4-5 months ago. I never noticed any side effects other than right after I put it in for the very first time and then I just got a little light headed which I attributed to the fact that I have never taken birth control before. I am 30. Now I am wondering if what is going on is side effects from the birth control or if I may possibly be pregnant. The last time I did the deed ws about 4 weeks ago, when my guy was in town, since then I have taken the ring out to get my period and put in a new one. However, for the past few weeks, since he left I am feeling nauseaus, like I am in the bathroom all the time at night some nights, not getting very good nights of sleep and having crazy dreams, for about a week the smell of coffee made me nauseaus and this all happened after he left. I didn't feel any of these things prior to that at all since starting the birth control. I also occassionally feel cramping, bloating and back pain and moody, which I typically experience with my period but I don't take it out for that for another 2 weeks. I have read that these can be side effects and my girlfriend said that they probably are side effects of the birth control so maybe I should stop taking it. Part of my says she may be right the other part of me wonders why it would take take this long for the side effects to show up. Has anybody out there used the Nuvaring and experienced similar side effects or experiences or gotten pregnant while using it?? Encouraging words needed. Thank you!
