Simplifying terms

April • Age: 22/27 and trying for babe number 2 but different partner.
Can anyone explain all the simplified terms? 
​So confused been using Glow for jay over a month now and haven't really looked at the experience and thought I'd join in on them but a little lost!!
​I am 22 and trying for my second, its not with my little boys father and we have been trying for 8 months now and still no success I'm on a 25 day cycle and fertile now, highest chance is today and tomorrow!! 
​If anyone wants to buddy up and in the same situation be nice to meet someone. :)
