How long does it for trinessa (norgestimate and ethinyl estradiol) to be effective?

Day1-5 ok right away: You are protected against pregnancy right away if you take it during the first 5 days after your period starts. So if your period starts on monday, you can start the pill up to friday for instant protection. If you start on day #6 or later, then it takes about a week before you're fully protected & so you should use a back up method (condom, female condom, diaphragm, or sponge) during the 1st week.

Trinessa (norgestimate and ethinyl estradiol): It depends on when you started and how long your perioids are without bcp, generally speaking most peroids can range from 4-7 days. With trinessa (norgestimate and ethinyl estradiol) your cycle should become more predictable and steady with proper use.

Possibly.: Trinessa (norgestimate and ethinyl estradiol) effects progestrone & estrogen in your body. If you don't have enough progestrone than you have lack of period (amenorrhea), hypermenorrhea & breakthrough bleeding. If you don't have enough estrogen you could have spotting, hypomenorrhea or breakthrough bleeding.

Birth control pill: Trinessa (norgestimate and ethinyl estradiol) prevents pregnancy by: 1. Preventing ovulation 2. Changing cervical mucus so the sperm can't fertilize an egg as easily 3. Changing the lining of the uterus so a fertilized egg will be less likely to implant. Birth control pills like trinessa (norgestimate and ethinyl estradiol) can make periods regular & easier & lower the risk of ovarian cysts. It doesn't protect against stds. Use condoms & get tested @ sexualhealth.Com.
