It took us a year with our first, but tried not to stress overy it. The moment you relax, it will happen for you, good luck to anyone trying!
FYI, MissCassy is a big fat catfish of epic proportions. She's a previously banned user (one of the ones that were a legit banning) who keeps coming back and trying to pretend to be someone else to get on a BMB. One of my fellow BMB members sleuthed this out like an FBI agent on a mission. MissCassy was created using a stolen pic from FB of one of her IRL friends. How she hasn't been IP banned at this point is beyond me. She's sick and needs serious help.
We got pregnant our first month of 'not, not trying'. We expected it to take much longer and were very surprised, but are also very grateful for this pregnancy.
