Baby flutters

Lindsay • Baby #4 on the way!
Just trying to get opinions. This is my 4th time going through the first trimester. My first needed in mc at 13 weeks and I have 2 healthy kids. My question is, how many moms have felt baby flutters in the first trimester? With my first healthy baby I felt him at 12.5 weeks. I felt my second at 13 weeks. I'm 12 weeks now and I swear I feel tiny flutters here and there. I have a friend who is a first time mom and she is 15 weeks and not feeling anything. She swears I'm making this up. Thoughts?
