If you have been taking them consistently since your last period it does not matter what time of day you take it or when you have sex, for that matter. More important is the consistent daily use. ...Read more

I was on ortho micronor from 1/23/17 til 2/19/17 and was wondering how long it will take for me to get pregnant?
Short half life: Progesterone only birth control pills have a very short half life meaning they are out of your system shortly after you stop taking them. Within about one week one returns to their normal baseline fertility. We can not predict how fast an individual will get pregnant as that depends on your baseline fertility ...Read more
I have stopped taking Micronor 13 days ago. I've been experiencing pregnancy symptoms, but have had 3 negative test. Are these symptoms from the pill?
Sounds like no: If your pregnancy symptoms were caused by pregnancy then that implies that your pregnancy hormones would be high enough for detection by a pregnancy test.

I'm on the Micronor (norethindrone) pill, have been irregular for the past week. I had unprotected sex. I had 2 pills before sex to make up, am I safe? What do I do
Take Plan B: Micronor (norethindrone) is most effective if you are also breast-feeding. If you are missing pills (and not taking them at around the same time every day) your chances of pregnancy are increased and its recommended that you use a back-up method such as condoms to prevent pregnancy. Taking 2 pills in one day will work if you only missed one pill the day before but if you have missed more than that it may not. ...Read more

On Micronor (norethindrone) (norethisterone) taken at 9pm everyday, I had unprotected sex on Tuesday, took pill that night but forgot Wednesday. Pregnancy possible?
Pregnancy: Pregnancy is always possible in the reproductive age group. The likelihood in your case is low assuming that you caught up by taking both the pill you forgot as well as the one for that day. Run a pregnancy test to be sure and let this be a lesson. ...Read more
Take precautions: If you forgot to take the pill at any time, you should take the pill when you remember it and then take the next pill at the regularly scheduled time. Then, using a back-up method will provide security of not getting pregnant. Having forgot the pill 2 days after intercourse will probably not increase your chance of pregnancy. ...Read more
Hard to tell: Micronor (norethindrone) is a progestin-only (single ingredient) minipill. It is hard to tell if a woman taking Micronor (norethindrone) every day actually ovulates or not.

If she misses some pills, she can use condoms for the next 2 days (if having sex)... while also taking the Micronor (norethindrone) every day. ...Read more
