Acronyms???

Jamie • Long time nanny, wanna be Mommy! Both of us have baby fever!
Hello,
​I'm brand new to GLOW & I've been reading through the topics & trying to figure out what all of the acronyms stand for.... Can anyone help me learn them please??
​for example, the only one I really know what it means is:
​TTC- trying to conceive
​Can anyone else list them out for me & others whoay be confused??
​Thank you in advance!
​Jamie
