The Gal Pals (formerly ibeauty.com) - iVillage fertility planner

If you're trying to conceive, you know how frustrating it can be to track your fertility cycle. (And getting pregnant is supposed to be the fun part, right?) The iVillage Fertility Planner takes the guesswork out of conceiving.
The online planner at iVillage was developed with fertility expert Toni Weschler, from FDA-approved technology, to include all the tools couples want most, including an ovulation calculator that pinpoints the best days to try and forecasts that can predict your baby's due date.
