Has anyone used a fertility monitor? I had a mc on December 26th, got my period January 25th and completely thought I was good to go BUT then I just had a 40+ day cycle =( I'm actively ttc and I really don't like the opk pee sticks (I get very fixated on the lines and whether they were as dark as the control, darker the day before, etc.). The monitors are quite expensive (to me at least) and I was hoping someone could steer me in the right direction (buy/don't buy...brands that people like...) Thanks!
