when does your baby start moving

If you're truly feeling some movement this early (which almost no one does) and you're looking big it's possible that you're having multiples. But, you might just be feeling what you want to feel. It's very common to feel all sorts of things going on in your abdomen that feel like they might be baby movements. Generally, women don't start feeling a baby move before 16 weeks, the average is somewhere around 18-22 weeks.

I felt my first baby move around 19 weeks. I thought I felt my second move at 12 weeks but didn't feel anything reliable until 16-17 weeks. I'm now in my third pregnancy and I started feeling movements at 18 weeks and now at 20 weeks I'm almost positive that I can feel two distinct babies. (Ultrasound in two days, so we'll see...)
