Maybe starting to try to have a baby!!:D

My SO is in town for the night and we always send each other goodnight messages. In the message he was saying he can't wait till we have a family and get married(the usual) but he just said he's thinking about wanting to start to have a baby!! I don't know why but I'm so nervous right now,and excited all into one!! He's known for a while now and I just can't believe it!! In May we will be together for 3 years:):) he's 20 in May! I know people might say I got a lot of partying to get out of my system,etc but I've been done with that long ago and don't hang with that crowd anymore! Just seeing so many people my age starting their own family made me want that so much sooner:) how long did it take for you to concieve?!
