Am 18 and my girlfriend is 16. We had sex for the first time day before yesterday whike she was on her period. I used a condom to start with after I ejaculated I threw the condomaway and later mated again wwithout peeing or wahsing my penis.. I repeat she was on her periods and it was her 4th day. So nothing has happened except her vagina was burning and hurting a lot an hour after we were done and it gradually decresed and she didn't bleed the next day. While the second time I didn't ejaculate Inside rather I pulled out and ejaculated outside. Is there any chance of her getting pregnant?

Of course. Any time you have sex, you have the chance to get pregnant.

Of course. Any time you have sex, you have the chance to get pregnant.

In accor to what u just replied I didn't ejaculate inside maybe the precum got away and I have read over the Internet that the sperms die as they hit menstrual blood.. open for advices!

Accordance*

ANY time there is penile insertion, there is the risk of pregnancy. You can minimize the risk, but not eliminate it. So yes, she could become pregnant. You will not know until her next period is due. If she doesn't get it, then you have to wait another 2 weeks to start testing.

On a separate note. Have you heard the term "Jail bait"? Depending on local laws she may be under the age of consent, which could land you in jail.

I have read over the Internet that the sperms die as they hit menstrual blood

The internet is a dangerous place to get information for those who don't know how to use it properly.

Women get pregnant on their period all the time. What you "read" is factually incorrect. So, yes, she could very well be pregnant.

What you need is some factual information on the birds and the bees, not just what you find on Google.

Better read again, women get pregnant on their period all the time, I have a son Chuck Jr, that is proof of that one.

While the chances reduce, yes there is a chance.

Also, should have keep new condom or no sex. There is a chance even with condom, condoms have a 3 to 18 percent failure rate, according to the last info I have from Planned Parenthood.

So perhaps spend the next month, till she has another period, picking out possible baby names, it may help you consider birth control next time
