Fly ferning is a method of predicting ovulation with saliva. You can get a kit for it, it involves looking at your saliva through a little microscope. The idea is when it looks like 'ferns' you're fertile. I think that was how it worked anyway, it's been a while!
Nervous How was your scan? I hope your dog is doing okay. They're part of the family, it's totally normal to worry. Our old dog had a lump on her side for years, she developed a few as she got older. I can't remember what they were now but they were harmless. I hope your dog's is the same.
Lily Yay for EWCM and positive OPKs! Very exciting! Go make the most of it 
Meamomma welcome! It's impossible not to symptom spot isn't it?
DizzyN I love FF but it can be really frustrating at times. If it's right about ovulation would your chances be good this cycle? If so, I hope it's right!
Sammy some chill out time is always good! It sounds like your clinic are really proactive, and you're right knowledge is power especially when TTC!
I'm a bit worried today, as I said I've been feeling like AF is coming and now I've had some spotting. It's only CD17. What the hell does my uterus think it's doing?
