Ay anak, I understand why you're worried, that's our mommy instinct, diba? But please go see your OB as soon as you can para ma-check properly, especially if this is unusual for you. At 17 weeks, movements can still be very light or you might not feel them yet (lalo na kung first time mom ka or kung anterior placenta), pero your doctor needs to confirm lahat is okay lang. Don't wait, ha, better safe than sorry, and peace of mind mo is worth it. Let me know what the doctor says, okay? Sending you a tight hug!
