Can a 13 year old get pregnant with out any?
A thirteen year old girl can get pregnant if she has started ovulating and has unprotected sex.
12-13 year old girls should not be having sex and YES you CAN get pregnant if you are ovulating (having your period) 12-13 year old boys can also get them pregnant. Boys can begin ejaculating as early as 10 years old. There could be 10 yr old boys producing sperm. This is not often, but certainly possible.
If a girl is 13 and pregnant by an 18 year old can the no contact order be lifted so he can be around for the kid?
I would hope the official legal answer is no. Due to the fact that the 18 should not be around a 13 year old in any capacity. 13 year olds should not be thinking about sex, much less acting on it, they are entirely to young. That is staturatory rape and I would hope the 18 year old is tucked safely into jail.
