You don't leave it in four weeks. If you did, there wouldn't be a week without it. You would go from the fourth week right into the next ring. If you don't leave them in long enough, there is a chance of getting pregnant. << doesn't know what they are talking about really... ok so actual answer: nuva ring has an extra week safety net if you forget to take it out at the end of the 3rd week you have an extra week... just take it out at the end of that 4th week leave it out for a week and resume use take it out after three weeks :)
Breakthrough bleeding may last for days or weeks when you skip a period with hormonal birth control. Typically, it just lasts for a few days.
If you inserted NuvaRing during your period, you're likely to bleed again in two to four weeks.
Inserting NuvaRing during your period is likely to slow bleeding, but it may not stop altogether. Starting NuvaRing during the first five days of bleeding gives immediate pregnancy protection.
You can skip your period for as long as you like (there is no maximum) or not at all, depending on your preferences.

NuvaRing remains effective for up to four weeks after inserting it. If you leave it in for the four weeks, though, be sure to insert the next ring at the end of the four weeks; don't take a ring-free week unless you had it in for just three weeks.

The question is a little confusing... You left it in for the 4 weeks so that you could skip 1 months withdrawal period. Then you took it out for 1 week to have the withdrawal period at the beginning of the next session. Did you reinsert a new ring after the 1st week of the new session?
