Not feeling movement

Hi ladies I’ll be 16 weeks tomorrow and this is my 3rd baby. I haven’t felt baby move yet, anyone else in the same boat. I sure would feel better if I knew she was wiggling around. I know it can still be early but you know us moms worry all the time. Just wanting to know I’m not alone. I have an OB check up tomorrow. I can’t remember when I felt my 1st move, 2nd one I felt early on. I think I’m nervous because my OB couldn’t find the heartbeat with the Doppler at my 12 week appointment, I had to have an ultrasound.
