how effective is the nuvaring

The NuvaRing is highly effective as a contraceptive method. With perfect use, it has about a 99.7% effectiveness rate, meaning fewer than 1 in 100 women using it correctly for a year will become pregnant. Typical use, which accounts for occasional use errors, brings its effectiveness to around 91%. If inserted within the first five days of menstruation, it provides immediate pregnancy protection; otherwise, it takes about seven days to become effective, requiring backup contraception during that time. The NuvaRing works by releasing estrogen and progestin hormones that prevent ovulation and thicken cervical mucus, reducing the chance of sperm reaching an egg. It is more convenient than daily pills as it is used once a month. However, it does not protect against sexually transmitted infections (STIs) and can have side effects like spotting, breast tenderness, or nausea. Overall, NuvaRing is comparable in effectiveness to combined oral contraceptives and offers the benefit of not requiring daily dosing. Correct and consistent use is key to maintaining its high effectiveness.
