Baby Girl moves alot!!!

Adriana • First Time Mom, can't wait to meet my little love Nov, 10. 2016
So I am 18 weeks , first time mom. My baby moves alot, I can feel her move 6 times a day or more , this just started like 4 days ago. Before when I was 14 weeks I wasn't sure if it was her moving, but now I'm so positively sure it's her. Before bedtime my husband and I lay down and try to see where she , my husband calls it "hide and seek" . It's so amazing that she is moving this much with only 18 weeks. Even when we went in for my appointment, doctor was using a doppler to hear her heartbeat, but doctor said she couldn't find her because she was moving too much, it took her a while to find my baby. So does this mean she's healthy being so active now??
