NuvaRing is considered a very safe method of contraception. Because it doesn’t have a lot of estrogen compared to other types of combined birth control, there’s a lower risk of estrogenic side effects like heavy bleeding, water retention and nausea. It’s quite common to get side effects when starting a new birth control method, but they’re usually mild and go away on their own after a month or two.
However, any birth control containing estrogen may slightly increase the risk of certain health problems. Complications from NuvaRing are extremely rare but serious side effects are possible, so you should speak to a doctor if you notice anything that concerns you.
