hello milney.It is quite normal to not have fallen preganant yet.Have a look in the TTC forums and you can talk to others in the same boat.I took 4 months for my first child and i am trying for the second.I charted with my first child and i think 4 months is not really a long time to fall pregnant but that is just my opinion.My SIL took 3 yrs and that is long! You will find alot of helpful people on this website.
