My girlfriend uses the NuvaRing and is also an OB nurse. As long as the ring is in place it continues to release hormones in your body which prevent you from getting pregnant. It won't just stop releasing these hormones after the 21 day cycle. I'm not sure exactly how long it would take for all the hormones to be released but 2 days is certainly not a long enough time.
Since you reinserted NuvaRing two days late, there's a chance you could be pregnant. Take a pregnancy test, and use a backup method of birth control until you've been on the ring for seven days. if you don't get a period after removing NuvaRing, repeat the pregnancy test. If it's negative, insert the new ring.
Seven days is normal. Five will work, particularly if you want to change your ring change day to two days earlier in the week.
If you have had unprotected sex, and now you are two days late , then you could very well be pregnant.
You should start using your ring for the first time after your period has stopped. Then begin using your timer to remove on the correct day and replace 7 days later. If used properly you should never have any problems. I was on the ring for 6 + years and had sex as soon as the same day I put it in and never had a question about pregnancy. I fully trust the ring as my method of BC.
When women use hormonal contraception like the regular birth control pill, the patch, or the ring, some will already have started ripening an egg for next months ovulation after seven days without hormones (i.e. during the pill-/ring-/patch-free week). For that reason, missing pills (or being late with your ring) early in the cycle is the riskiest for accidental pregnancy. If you're late inserting your ring:Use a back up method, like condoms or abstinence from vaginal sex, for the next seven days;Consider using emergency contraception (e.g. the morning after pill) if you've had sex during the days you were supposed to have a ring in;Write down that your new ring change day will be the same day of the week that you inserted this one.
Being on NuvaRing prevents pregnancy; stopping NuvaRing means you no longer have pregnancy protection. There is no special fertility turbo boost from recently stopping birth control.
You can be up to two weeks late and not be pregnant but to be safe you should take a pregnancy test after you are seven days late.
If you inserted NuvaRing during your period, you're likely to bleed again in two to four weeks.
you should see your doctor
Yes
If the egg becomes fertilized, yes.
Possible if you had sex in the last 14 days. Most likely you aren't. Two days late is nothing and it could be caused by stress, sickness, or you miscounted. When you are a full cycle late do a test, but my bet is you will start in the next week.
