Excellent product! We are 2 months' pregnant with out second child. :-) I am 37 with PCOS (quite full on hairy chin etc..,) We were trying for 1.5 years but only 4 months with Mira. It was interesting to see how my cycles and hormones worked. It was really helpful for forward planning. We already have a child and busy lives, so we don't have time to do the baby dance every other day throughout the month. So this really helped us pinpoint the right time. We actually got pregnant by doing the baby dance 3 days before ovulation day, so if we'd used the ClearBlue smiley face method, I doubt we'd be pregnant now! We did combine this with changes to health, diet and exercise of course.
