Lolo, I can't say I nnoticed any changes with any of my pregnancies in the beginning - but as I got further along I had tons and tons of watery and creamy fluid. But then again, maybe I didn't notice any changes because I didnt have to work so hard for it last tIke so I didn't have to pay so much attention! I'm sure everybody's different though, and just because you may not have "typical" pregnancy signs doesn't mean you aren't pregnant. I started testing early last cycle too. Good luck!
Greenie, did you wake up early on any of the days where your temp is lower? Or maybe sleep in and wake up later on the days when your temp was higher? I know, personally, my temp is always really sensitive and even an hour or 2 will make a huge difference in my temp. Which is why i dont temp kow that im working nights. And also, just remember your temp may not make a huge jump, so it may just be a more subtle change in temp, and you won't notice until you've had 3 days of slightly higher temps.
