Lingo??

OK so I just started using glow app and so far I love it.. it's very easy to track an great tips an advice. Before glow I was using another period tracking app but it didn't have a way to communicate with other women who r going thru the same thing as u. So some of the abbreviations used are a little Confusing to me. I'm trying for my first baby so I'm not familiar with all the pregnant abbreviations or talk.. Please help for I am a little lost :) lol
