How long does it take to get pregnant :(

Seriously! I feel like this is taking forever :( I always thought "oh as soon as we start trying we will get pregnant!" But now we are on cycle four.... Which I know that's not long at all! But it is longer than expected :( how long did it take you all to get pregnant with your first?! We are dilligently tracking ovulation and bd on all the right days... It just hasn't happened yet :(
