Pregnancy Calculator 2.72

Pregnancy Calculator is a simple application that will show you what are the best dates to conceive a child. The first thing to do is click on the first day of your last period. Then, the program will calculate when the baby should be conceived or was conceived, in case you are already pregnant. It will also show the start of the second and third semesters, the possible dates of the baby's arrival, how many weeks and days you are pregnant, how many weeks and days left for the delivery, the expected delivery date, and the baby's astrological sign. All these results can be printed, so you can have them at hand.

Another interesting aspect of this application is that you can also select the desired delivery date, and the program will automatically calculate the probable dates of conception.
Unfortunately, the application is based on a regular menstrual cycle of 28 days, so if you have an irregular one, the program won't help you. You cannot enter the length of your luteal phase either. Another drawback is the lack of customization options. The user interface is extremely simple, but definitely unattractive.

In short, if you are looking for a simple and free application to predict the best conception dates or to know how far advanced your pregnancy is, Pregnancy Calculator may work for you, but don't expect much from it.
