It really depends on age, how long you have tried etc. Our first took 2 weeks.. LOL Surprise. The second took a year of trying. My loving SIL said have sex every day! Thanks!
Seriously, I was pushing 39 so my doc put me on meds that made me ovulate. 1/10 chance of twins. However, I forgot to get perscription renewed due to crazy schedule and one morning I woke up sick. Peed on a stick and viola! I think we both were not thinking about it because we had other issues to deal with. You are young, dont stress! Woohoo, what an adventure you are on!
