Lucky #7???

Is 7 really a lucky number like people say??? Im getting ready to find out.. im starting my 7th month of fertility meds ( 2 years in the making) and we shall see :) On Wed i start the 7.5 mg of Letrozole and will take it for 5 days. Later on this week the nurse will call me back to schedule a midcycle ultrasound to see what things are doing in there :) I hope alot!!!! I will keep ya'll posted on what goes on.. but for right now, we pray... we pray really hard that this works bc im at my whits end here!!!! Thanks :)
