Are you TTC checking BBT with STM and wondering if your OPK caught LH this cycle?
Or perhaps you’re new to FABMs and TTA, and you recall your LMP but can’t tell on which CD your LP began.
If you decoded both of those sentences, consider yourself fertility awareness user level: EXPERT.
Medical jargon has long been known to include a wide array of cryptic acronyms, yet a quick google search will reveal the meaning of most of them. However, many women find themselves wading through a similar alphabet soup in the world of cycle charting – and the same internet search won’t always yield helpful results!
New and seasoned cycle charters alike may engage in classes, webinars, or internet based groups seeking advice and support. But sometimes, it can be difficult to keep up with clinicians or peers when the language seems to be spoken or written in code. If acronyms have been a roadblock to understanding these discussions in the past, we’ve complied a comprehensive list of commonly used and important acronyms to navigate the world of fertility awareness based methods. The best part about this guide? It’s universal – it isn’t method or user specific.
So the next time, you will be the first to answer when someone asks, “What CD does AF start on?”
