Found out why I can't feel my baby kick

This is baby number three and I will be 20 weeks in 2 days. I was really stressed because I haven't felt any kicks, and with both of my others I felt tons by this time. Found out that I have an anterior placenta, which just means it's in the front. It's more layers for the Baby to get through, which is why I can't feel her yet. Just thought I would share in case any of you are stressed about not feeling movement
