I am 22 years old and 29 weeks preggy at the moment.
My fiancee and I were planning on having a baby in a few more years but we weren't using protection or anything so we knew that if it happened earlier than it happened, and we would happy and would accept it.
I kinda hoped at some points that I would be pregnant. Something in me just wanted to be a mommy and I just wanted to have a baby.
Once we found out that I was pregnant we had a talk where my fiancee admitted that sometimes he kinda hoped that I would get pregnant. Something inside of him just wanted it, but he never said anything. Everything was just planning for the future.
Now we are very happy and expecting our first baby!
I think that this feeling comes naturally for those who have that maternal instinct and I think that many people feel it at some point. Whether "the time is right" or not.
Good luck with everything!
