Actually, yes. The way it is for my period while on Nuvaring is after three days of it being out, my period starts. It's like clockwork. But I recall the first time I used Nuvaring my period was about a week and a half late. I was freaking out too because I thought I was pregnant. But luckily, I got my period.
If you have a period than you are not pregnant
No. You can get pregnant in the week(s) before your first period.
You can pregnant at anytime before after or during
You can get pregnant a week before your period, the week of your period, and the week after your period, and some pregnancy tests are faulty.
Yes, you can get pregnant in any point of the menstrual cycle. When your on your period, a week before, etc. You are most likely to get pregnant when your ovulating, which I think is a week or two before you come on your period.
If you are trying to get pregnant, you should leave the NuvaRing out. There is no sensible reason to use NuvaRing on any schedule when you're trying to get pregnant. Talk with your health care provider to clear up your confusion on this issue, and on how conception happens.
If you use NuvaRing correctly, you are protected when bleeding and when not bleeding. If you have the NuvaRing in for the previous three week, you are protected during the ring-free week as well.
The first week after, and the last week before a woman's period.
You can get pregnant at any time. Including during your period.
