Success rate of taking Plan B within 41 hours after condom broke ?

High: Pregnancy rate is ~10% if taken within 72 hours. There may be irregular bleeding for up to 2 months after taking. The pattern doesn't mean anything about whether the medication worked or not. So run a home urine pregnancy test 14 days after the accident using first urine of the morning. If it's negative, you're not pregnant. Consider a more reliable form of contraception for the future. ...Read more

I experienced condom failure with my wife 2 days in a row and we've used plan b within an hour of each failure. Is this safe and will it be effective?

Likely will work: Plan B can alter the menstrual bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too. One should check a home pregnancy test about 3 weeks after sex, because Plan B works most of the time, but not all the time. ...Read more

If one truly doesn't want to become pregnant, using Plan B is pretty effective and can be taken as soon as possible. One can call her Ob-Gyn doctor if having questions or concerns. ...Read more

Is it normal to have mild cramping & nausea for 5 days, that began a couple hrs after taking Plan b? Took it 3 hrs after condom failure. I have not go

For the most part: you should expect a fairly extreme period with some cramping and stomach symptoms after taking plan B. It is after all supposed to wipe out your current hormonal situation and induce a massive overhaul in order to disrupt the normal fertilization cycle. It is kind of like a tsunami of hormones.

I am on regular birth control pills. I took Plan B the first day of my placebo week because of condom failure. Could Plan B make me miss my period?

I am on regular birth control pills. I took Plan B the first day of my placebo week because of condom failure. Could Plan B make me miss my period?

Maybe: If you were taking the birth control pills regularly it is very unlikely that you would become pregnant...Even with a broken condom. The condom is helping very little with your contraception but using a condom can be a good way to prevent some stds, not all. Plan b could alter your period. Just begin your next pill cycle on the correct day. Get a pregnancy test done to prove you are not pregnant. ...Read more
