Are you trying to get pregnant? BabyCenter.com wants to help by sending a text message alert to remind you it's time to get it on if you want to get preggers.

The mobile fertility alert, which is called -- I kid you not -- the Booty Caller (the Spanish language version is called Mama Cita), will send three messages during each menstrual cycle to let you know when you are a week away from being a Fertile Myrtle; when the fertile period starts; and when you are down to your final day. Check out this sample message: "Your fertile window opens today and lasts 5 more days. Stress can get in the way of conception so relax and get a massage, meditate, or take a yoga class."

The service is free to BabyCenter users who provide basic information on their menstrual cycles. However, standard text messaging rates apply from your cell provider.

Now, how you make sure that you and your significant other are in the zone on those days is up to you.
