Most times it takes multiple tests however, at this point a blood test by your doctor is your best bet.
Yes ... and ... pregnancy could occur if it was only 1 time, too.
The only way that would be possible is if the sperm entered into the vagina. If the underwear was moved away from the vagina at anytime that the boy ejaculated or after and the sperm entered, than yea, it is possible. If there is absolutely no way that the sperm entered the vagina, then the answer would be no. Your call, we were not there.
Yes but it's harder. There's always a risk of pregnancy until you have entered menopause fully and menopause usually start around 50.
No, sperm cells are not active outside of the body that long.
Not possible unless you are sexually active and semen could have entered your vagina. If this worries you you will have to wait until you period. If you miss it after 5 days take a couple home pregnancy tests to be sure.
Very unlikely but the chance is still there.
Being underage is not preventing pregnancy as soon as you have entered puberty so yes. As a minor it's even more important to protect yourself and actually not have intercourse at all since it's illegal, but also because your body is not developed enough for pregnancy and childbirth even though you can get pregnant.
I'm going to go out on a limb here and say its quite impossible TO have a baby with an "intact cherry"...
It is very unlikely. If no semen entered the vagina, there can be no pregnancy. A little slippage is fairly normal.
no not as long as no semen has entered her
This question needs rewriting and can not be answered at this point. If you had sex and sperm entered/was around the uterus you could be pregnant.
YES
