Yes, it sounds really familiar. I am 36, just got married last year and H has no kids either. I should also mention I am gassy and feel like I've swallowed a watermelon!
I don't know anything about monitoring temps, how does that work?
By the way, what's wrong with all these HPTs anyway - negative after negative? <IMG SRC="http://www.healthboards.com/ubb/wink.gif"> When I got the negative test last Friday I kept saying to my girlfriend "I hate my pee!" LOL
