Ay anak, totally normal yan! At 17 weeks, what you're feeling ay probably quickening, yung unang movements ng baby, kaya exciting na exciting ka haha. A few of us moms felt the same paranoia on our first pregnancy, pero honestly, active babies ay usually a good sign, not something to worry about! Since this is your first time, it's always best to mention it sa OB mo next visit para peace of mind mo, pero I'm pretty sure sasabihin niya na okay lang yan. Congrats sa pregnancy!
