In the begginning of August my girlfriend and I were touching genetals. Rubbing, Grinding, whatever you want to call it. I didn't ejaculate at all but she got scared so I bought her the plan-b pill. 2.5 weeks later, after she ovulated, we had sex and I used a condom. Even though I used a condom I still pulled out and ejaculated in the condom. Because I finished quickly and was still arroused we decided to grind with the condom on. When we were grinding with the condom on, both naked, we noticed it had slipped up and she was rubbing the base of my penis. She freaked out because I had ejaculated in the condom and her vagina was rubbing the base so we called 8-10 pharmacist and asked the affects of taking the plan-b pill 2 times in one month and was told everything would be fine and it still has the same affect. So within the first hour we went and got/took plan-b. I just need to know other opinions of people on if you think she will become pregnant. Thank you.

I think the chances would be slim. Unless you noticed some of your semen leak out of the condom, and go into her vagina, then that would mean there was technically no contact with your fluids. But still, better to be safe.
Has she considered going on birth control?

Well we did plan-b within the first 24 hours twice. Will that play into it? And we have talked about it but she is finding it hard to get past her mom on that one.

All those reading and/or looking at this post please answer

No form of birth control is 100, including plan B

So is there a chance, yes,

Condoms are not 100 percent even when used correctly.

So while it is a very very small chance, yes there is a chance.

It is very obvious you know little about pregnancy, and should not be having "grinding" and sex until you do much more study on it.

When you said two and a half weeks later, after she ovulated... are you talking after a period or does she know when she most likely ovulates?

Regardless, odds are very slim she will be pregnant. However, certainly use some sort of birth control every single time to decrease the odds even more.

Just a tip: once you ejaculate, even into a condom, do not reenter her vagina. Peeing or washing also will not guarantee sperm are not still present. Just one of the main ways couples misuse condoms.

She knows when she ovulates. So It was after she had completely ovulated. I didn't reenter her after ejaculating. Jus grinded. Thank you so much for replying.

If it was indeed after she ovulated, which the egg is only viable for about 24 hours, then there is no way she would become pregnant.

The wording of it being "after she completely ovulated" still leads me to wonder whether when she has her period and when she ovulates (two different times in a cycle) are being confused. Perhaps I am incorrect, it is just the wording, and she is fully aware.

She is supposed to start today. She knows when she ovulates and has shared that with me. Also since she took plan-b twice can that delay her period?

Yes, it can definitely alter her period. Did she have some bleeding several days after she took it?
If her period is off, give it a week or so and she can always try a pregnancy test if it still doesn't show.

She did not and okay good to know. Thank you so much! She's supposed to start today but if she doesn't I shouldn't worry?

You will even if I told you not to... :) Periods can be off a few days here and there for not apparent reason. If it doesn't show after another week or two, then she should try a pregnancy test. If she did ovulate about the time she thinks she would have, she wouldn't be pregnant from sex two and a half weeks later.

It was 2.5 weeks after the first time she took plan-b. it was about a week after she ovulated.

The only way a woman can become pregnant is to have sperm waiting to fertilize the egg at ovulation. The egg is viable for about 24 hours once ovulation occurs... the earlier in that 24 hour period the better. Sperm can live for several days just before ovulation occurs. They will die off fairly quickly at any other time of the month and there is no egg at any other time of the month.

Again, if she is right on when she most likely ovulated, she wouldn't get pregnant.

Thank you for all your help! She started today around noon!

Whew! Glad you both can rest easy... but do be careful in the future to avoid unnecessary worry.
