Hey ladies! I'm new to the Glow community ( been using the app since November though) and I feel so lost reading some posts. I see abbreviations like AF (Aunt Flo?) BFN and BFP, etc. I finally figured out opk is ovulation prediction kit but sometimes I'm so confused. 2ww? Is that the 2 week wait between ovulation and period?
