All these abbreviations...??

Carrie
Hi all you rosy glowy pregnant/ttc people!! I'm new to the app, 4 Weeks and 3 days preggo with my first child. I've been really enjoying the community and all the different forums to post on and read through, but man you guys use a lot of abbreviations! So far I've only picked up on TTC (notice how I used it before, trying to be hip) Is there some kind of post or setting within the app that goes over what all these are supposed to mean? I can't think of any off the top of my head now, wait maybe one of them is BFP? Anyway I'd appreciate if anyone can point me in the right direction on where to look these up, or please just list a few or any below that you may happen to know. Thank you all!
