14 weeks with my first, 13 weeks with my second and 15 weeks with my third. The smaller you are and position of baby can make it to where u can feel it sooner than most
I was around 18 weeks it was more like bubbles with my son then with my daughter same thing but I don't think I felt real kicks until 25 weeks or so. It does feel like gas, 12 weeks is early but if you've been pregnant before then it's possible. Congratulations! I can't wait to be pregnant again! It's amazing!
