How spot on is everyone else's fertile window on this app? I am thinking about getting a few ovulation tests just to be positive!!! We are TTC #1 and my fiancé is 35 I feel like we're "running out of time". We have been trying for a little over a year already..... I'm also thinking about trying the product "conceive plus" if any of you have used it please tell me if it has worked or if it's a waste of time!!! Thanks! (-:
