How many of us are on fertilityfriend? I've been using it for over a year and we paid for the 3 month membership. Right now I am tempted to pay for another 3 month membership since we are trying again, but every time I am about to sign up, it's our TWW and I tell myself that if we are successful it would be a waste of money. Who else is on fertilityfriend? Do you have a paid membership or do you just use the free version?
