When NuvaRing is in, it is releasing hormones in your body. When you take out NuvaRing that hormone level goes down, and you have bleeding or spotting.
NuvaRing gradually releases small amounts of hormones which are meant to prevent pregnancy. The ring does NOT protect against HIV or STDs. Any information you need on the ring can be found on NuvaRing's main website. Hope this helps.
My girlfriend uses the nuvaring and is also an OB nurse. As long as the ring is in place it continues to release hormones in your body which prevent you from getting pregnant. It won't just stop releasing these hormones after the 21 day cycle. I'm not sure exactly how long it would take for all the hormones to be released but 2 days is certainly not a long enough time.
The NuvaRing prevents ovulation by releasing a combination of estrogen and progestin hormones into the bloodstream. These hormones work by inhibiting the body's natural hormonal signals that trigger the release of an egg from the ovaries. Additionally, the hormones thicken cervical mucus, making it more difficult for sperm to enter the uterus, and alter the uterine lining to reduce the likelihood of implantation. Together, these mechanisms effectively reduce the chance of pregnancy.
