Why can't NuvaRing be worn on any day of the cycle?

NuvaRing works just like a pill containing a combined contraceptive (combined pill), but unlike a pill that should be taken daily, NuvaRing is used for 3 consecutive weeks. The disc secretes two female sex hormones that inhibit the release of eggs from the ovaries. Since the eggs are not released, the patient cannot become pregnant. If the patient wears NuvaRing on the first day of the cycle, she is protected immediately from pregnancy and there is no need for additional protection throughout the cycle. You can also start using NuvaRing between the 2nd and 5th day of your menstrual period, but in this case, an additional method of contraception (such as a male condom) should be used at the same time during the first 7 days of NuvaRing.
