Is there a sticky anywhere that gives all these abbreviations? I've figured a lot of them out, but like "HH" I couldn't figure for the life of me?! I also belong to a pregnancy and fertility forum and I know all the abbreviations for pregnancy test, ovulation predictor kit, Clear Blue Easy Fertility Monitor, and even semen analysis!!!!! BUT I CAN'T FIGURE THESE OUT!!! ARGH!!! HELP!!!
