Hey Sabrina! Welcome to the forum, my name is Jess and I'm the mother of a wonderful 2.5 year old.
When it comes to getting pregnant every womans body is different whether on ovulation days or not... where some woman can go years having unprotected sex and then randomly get pregnant, some woman get pregnant the 1st or second time having sex.
My only question for you is yes, you are in college, and yes you are married. But you are still only 18? Whats the urge? You guys have a whole life ahead of you to creat a family and be together? Whats the jump to have children?
