I think this app is great but in all honesty I'm completely stressed out because of it. I thought it was so easy to get pregnant and that's why I was on the pill for 7 years.. Now that I'm off it it just seems impossible and I am stressed to the max. And to know that you only have a 20-30% chance of even conceiving during your fertile window just gets me down even more. I think I should delete this app so that I don't over stress..I will miss it though and maybe next month I will download it again
