Don’t fret! I also started off baffled with all the abbreviations flying around pregnancy forums and it took many a googling to find out what they meant. Here, you’ll be able to get the A-Z on the most commonly used abbreviations. It isn’t an exhaustive list and there are many which I haven’t included simply because I haven’t personally come across them/there are just too many! However, if you want the whole shebang, you can find it here.
I have arranged the abbreviations by alphabetical order and by category so that it makes more sense.
