Uy, normal lang yan! A lot of us moms experienced the same thing, sometimes the dating from LMP ay off talaga, especially if your cycle ay hindi regular or if you ovulated later that month. The ultrasound dating is usually more accurate kaya yan ang gagamitin ng doctor mo going forward, so don't worry. Pero if you have any concerns or questions pa, definitely ask your OB during your next visit para ma-clarify lahat at you'll feel more at ease. Congrats sa pregnancy!
