If i had sex on day 14 does that mean that i'm going to get pregnant?

Sure, if...: If there is an egg waiting to be fertilized the following morning, and the sperm swim up to it, then yes, a baby starts. Usually, a baby embryo successfully makes it past the first few weeks, other times he or she does not survive. To raise a child, a couple should be married, settled down, and have stable jobs that provide good health insurance because babies have many doctor visits.
