I'm sixteen, I lost my virginity on November 13th we used a condom and checked it for holes filling it with water, he also pulled out before eyaculating. The same thing has happened another 2 times. My last period ended before the 13 of November, I don't remember very well. It's December 29th and I haven't gotten my period. Should I be worried? I'm scared and I don't know if it's just my nerves that keep on delaying it.

Please take a pregnancy test using first morning urine. I truly hope you are not pregnant and take this as a learning experience.

To add to what J_9 has said.

Condoms are only roughly 80% effective when used correctly and handled correctly... and next to no boys your age know how to do that correctly (they know more misconceptions and fallicies than they do facts) so odds are they are far less effective in this case.

There are no 100% effective forms of birth control. Even using condoms AND the pill its still possible to get pregnant.

Condoms should never be carried in a wallet or pocket (too hot and they are put under pressure, both damage a condom). They also have a shelf life so buying them from publc rest room vending machines means you have no idea how old they are.

Condoms are not 100 percent effective and of course withdrawal is far from effective. So yes, it is easy for you to be pregnant.

You need to be two weeks late on period before you can test. Always test with first urine of the morning
