Baby movements

So just curious when I can expect to start to feel movement? I will be at 15 weeks tomorrow and my belly is growing really slowly, still can't tell that it's a baby bump. I can't wait to feel movement anymore, I barely even know (for now still) that there is a baby in my belly. Growth was measured a week ahead at last ultrasound last week and my doctor said the development is moving along perfectly. This is my 1st baby obviously and I feel like if I can just feel the baby moving I will know everything is okay...
