The NuvaRing is a small flexible plastic ring inserted into the vagina to prevent pregnancy. According to Planned Parenthood, the hormones in NuvaRing are the same hormones as in the birth control pill, estrogen and progestin. These hormones work by inhibiting ovulation, altering the uterine lining and cervical mucous. Women can experience side effects after ending use of the NuvaRing.
The hormones present in NuvaRing might take some time to decrease in the body, resulting in menstrual irregularity. Women also might notice that their periods are heavier or lighter. These side effects should diminish as the body rids itself of the excess estrogen and progesterone. According to Planned Parenthood, after ring use is stopped, it usually takes one to two months for a woman's periods to return to the cycle she had before using it.
Women might experience amenorrhea, or an absence of menstruation after discontinuation of the NuvaRing. This can go on for as long as six months after stopping, and it is more likely to occur if your periods were irregular before using the ring, Planned Parenthood says. In some cases, amenorrhea might be a sign of pregnancy. Women who have had intercourse after stopping the ring and do not have a menstrual period might want to take a home pregnancy test.
It might take some time for a woman's fertility to return after removal of the NuvaRing. According to the manufacturer, results of a clinical study indicate that a return to normal ovulation typically occurs within 13 to 28 days after removing the ring. However, some women might take a longer to begin ovulating. Women should consult their physician if they experience infertility after using the ring. Certain methods---such as monitoring the body's basal body temperature, cervical mucous charting, and ovulation predictor kits---might be helpful at predicting ovulation and increasing the odds of conception.
