I found an okay one today, on Fertility Friend! I was using it to chart, but got bored when all my temps were the same for, like, 14 days, so I quit temping and filling in my chart, but then I found the pregnancy tracker. Basically, I am just bad remembering dates and stuff, and wanted a site to estimate my due date and tell me how far along I am. This one does the trick, although FF saves all the information about the baby and symptoms, etc for VIP members.
