Chances of pregnancy?

Chelsea • Baby 3 due April 2017 ❤️
I tried this a couple days ago but I've tracked my CM and my fertile window has changed according to glow and my other app. 
I suffered a miscarriage at the end of April, considering I'm not sure when my period is supposed to come, glow and my other app is telling me this is my fertile window what are the chances of pregnancy? Please give me your opinions.
