please don't judge me on this question...

okkay, I have a 29 day cycle, my CM has been really watery today, but I have 3 different fertility apps that all go off my period cycle. So my question is, ladies what is your favorite app to use for helping with figuring out ovulation dates? I feel so weird going off of apps because I don't know what ovulation symptoms are and I wasn't taught any of this by my mother, so if I could some help that would he amazing. my husband and I have been trying for 12 months now with no luck. I need some advice ladies if possible. all have a blessed day.
