Thanks, I'll check it out. I tried out the software that you can get with TCOYF, but couldn't see it. Maybe this one will be better.
ETA: I signed up for their charting stuff and I don't think it's quite right. Last cycle it puts me O'ing on CD 10, pregnant on CD 28, and gave me a 23 day LP. For some reason it completely ignored my OPKs. I'm not sure why it put in the pregnancy symbol. I'll try putting in other charts later, but for last cycle it's safe to say that it's very wrong unless my OPKs were conspiring against me.
ETA2: I got the rest of my charts plugged in and it gave me 2 cycles with the pregnancy symbol. That's just rude!
