Summer,
If you google "full moon" you will get some sites come up. If you take a peek youwill find a site that you can enter a date and it will tell you what phase the moon was in (eg your birthdate). This isn' tas accurate I believe as consulting someone who specialises in lunar fertility but I believe your lunar fertile begins approx 3 days prior to when the moon falls into the phase it was at your birth and for approx 24 hours after. It is believed that sexual activity prompts ovulation at this time. So in theory if youwant to conceive you need to get jiggy with it for about four days!
I will pop back on later and see if I can find the site that I found where you can enter your birth date... I had my chart done by an astrologist and that is how I know what my moon phase is however, I checked it with this site and it was the same...
