I purchased Maybe Baby back in June last year when we started TTC. I found that it did show when I was ovulated. To be honest I did forgot most mornings and would brush my teeth or something (you have to put a bit of saliva on the little thing and cannot eat or drink 3 hours prior). Anyway there is a maybe baby thread somewhere as some people like it and some people don't.

In the end we just DTD every night from about day 10 to day 20 figuring that would do. We did fall pregnant that way... 7 weeks later had a MC though.

Hope this helps... I also purchased a thermometer and again forgot to take my temp most mornings and didn't continue with that!
