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!
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
