I've been on NuvaRing for the past three weeks and decided today to abandon this contraceptive. I'm disappointed, especially because it's incredibly easy to use and doesn't give me the side effects i experienced on the pill (which included intense vomiting after one or two drinks). Only this morning did I realize that the irritability, lack of sex drive, migraines and depression I've been experiencing recently could be attributable to NuvaRing. I have been dealing with a massive workload recently and thought everything I was experiencing stemmed from that. But this morning after my boyfriend and I discussed my mood swings and complete lack of sex drive, I checked the side effects in the NuvaRing packet. No mention of loss of sex drive (can someone explain this--I feel like I've had tons of friends experience this side effect from hormonal contraceptives so why is not an official side effect?), but the packet advises women with a history of depression to consult with their doctor frequently. I have a history of depression (my doctor didn't inquire) and have been experiencing suicidal impulses the last two weeks for the first time in years. Though I originally attributed those impulses to overwork and exhaustion, I'm now wondering how much of this can be chalked up to NuvaRing.
