Moon calendars - says I'll be having her the 27th

Samara 🌸 • December 2015 baby momma-
So my sister told me to check how the moon was on the day I conceived , what ever  moon phase was on that day will be the same phase (this month) that I will have my baby. 
I conceived feb 6th and moon matches I'll be having my baby the 27th
Do any of you guys match your conceiving dates/delivery dates?
