Two weeks after unprotected sex is the first a pregnancy test would be accurate. It is most accurate after you've missed your period.

Listen to your doctor, and if you are still concerned about getting pregnant, use condoms with the nuvaring.

does the unprotected sex I had though before I went on nuvaring give me a good chance of getting pregnant?

a good chance? No, you took plan b (very promptly) and you were probably not really around the time of ovulation since you just getting off your period.. There is always a chance of pregnancy when you have sex, but in this case I wouldn't really consider it a good chance.

Yep, there is an error rate. Pregnancy is aways a possibility when you have sex.

Plan b isn't really meant to be used all the time, its only an emergency form of birth control and should never be relied on for normal use. Was this the quote you read?



I've never really heard that the more you use EC, the less effective it is. What they mean is that normal birth control is more effective than just plan b. Plan b, on it own and used correctly (within first 72 hours after sex) is about 85% effective. Birth control is about 92-99% effective. So obviously, the more you rely on EC, the more risk you have, which is why it's for emergencies only.

Notashamed, let me know if that's not the right quote, and if its not, do you think you could write in what the pack does say?

Maddie34 did a good job of explaining what Plan B means by being "less effective."

You're not supposed to rely on it as a form of birth control; it is EMERGENCY CONTRACEPTIVE. Therefore, used in the worst case scenario.

if you taking the plan b ills you shoudnt be worried about getting prego because it kills the cell eve before geting to your egg .

Hm... I'll keep looking too, but I can't find it saying that anywhere.

Plan b works almost the exact same way as birth control pills-- only a shorter and higher dosage of almost the same hormones (which is why some birth control pills can actually be used as EC). I've been looking, but I can't find one instance where it hints that a woman can acquire immunity to it-- if that were the case, then women would grow immune to using just regular birth control pills too-- which they don't.

I'm not saying you didn't see it, just that the wording is probably horrendously confusing-- which is annoying considering how much of a panic most women are when they are taking plan b.

Yes, plan b is not as effective as routine birth control, so don't use it like it is.
That's what I'm getting out of that.

It's like this (get ready, because I'm going to pull a hardcore statistic problem:D):
Say I had four marbles in a bag (one blue, three black) and I had to draw one marble and put it back into the bag after each time.

I have the same chance of picking the blue ball each time I draw, but the more times I do it, the more chance I have of becoming part of the 25% that draws a blue.

So Plan b is still effective 85% of the time, but you have more of a chance of falling in that unlucky 15% each time you use it. Does that make sense?

Well plan b doesn't always work even when taken correctly(within the first 72 hours), that's why it's only 85% effective and not 100%.

You took plan b the first two times and you fell into the "Yay! It worked!" group, whereas the last time you took it you fell into the much smaller "Oh poop, I'm preg" group.

Your chances were always 85% not pregnant. You just happen to draw the blue marble for your last draw and got stuck in the 15% pregnant.

It's like how women become pregnant on birth control. Was the birth control less effective even though they've been on it for 4 years? No. Are they stuck in the small percentage of women who get pregnant with perfect use of birth control? If sucks, but yes.

lol Obviously that's not what you said.. just some misplaced humor

I could also be wrong, but I just haven't found anything about someone growing an immunity to the effects of plan b or birth control due to repeated usage-- otherwise people would have to be changing birth control pills constantly!

I see where you are coming from, NotAshamed, but your logic is off.

You did A, which caused B to happen. That is horribly faulty logic. Just becuase you took it 3 times, and the third time it didn't work doesn't mean it decreases in effectiveness the more you use it.

That's like a superstituion. "I had a good day when I didn't walk under the ladder, and the one day I do walk under a ladder...my dog got run over. NEVER WALK UNDER A LADDER." See? Silly. It's called post hoc ergo propter hoc, a VERY common logical fallacy.

So, just letting you know you are letting your personal experience hinder the understanding of the actual thing. Not attacking you...just letting you know. And knowing is half the battle.

I think I know where we are getting mixed up, but I'll save it for now.

I'm going to the pharmacy tomorrow to pay off some bills so I'll just copy down your quote and ask for clarification. They seem to love helping when it comes to pregnancy prevention so it won't be a problem.

NotAshamed, gotta say...I am offended that you question my ability to read and comprehend. I was not attacking you, but you blatantly did that to me. I don't appreciate that in a debate.

To display my knowledge of English, I will explain my understanding of accumulate: to build up over time. Ok? Are you satisfied?

ALL birth control failure rates are accumulations over a period of a year. It doens't mean that EACH time you use it, this is what you have the potential to fail...it talks about over the course of a year.

You know that quote you gave? It tells you to see Table 2, and the Warnings page. Table 2 is an incredibly important piece to understanding this effectiveness piece. I've supplied the table below, with some alterations that I will explain:



You'll notice I took the liberty of circling the title of the table, which is important. Over the course of a year, this is the effectiveness of each birth control. Notice how most BC methods have 3 columns, because it takes into account repeated use. Right? So, ALL these failure rates are ALREADY ACCUMULATED (thus giving the second half to that quote you keep citing).

The below red circle (also denoted with a number 2) shows that EC methods are not really intended to be a primary source of birth control. They do not have three columns because they assume people are using it only when they need to (not whenever they have sex). The quote you gave REFERENCES THIS TABLE, which shows how less effective that routine birth control is, hence it being less effective over time (i.e. after time has accumulated).

Not enough? Go HERE for more info. Here is the direct quote I want the readers of this post to note:



Plan B does not lose effectiveness. It simply is NOT as effective as regular use of birth control pills or a shot. It is good to use if there is a situation (broken condom, missed pills, etc) of unprotected sex, but don't use it as a reliable source because as time ACCUMULATES, it is less effective as regular birth control. The quote you use assumes that it is understood that ALL failure rates are accumulated.

Do not make remarks questioning my intelligence. I did no such thing in my post to you.
