Ay, ganyan talaga sometimes, mama! The difference between LMP at ultrasound dates ay pretty normal kasi hindi perfectly accurate ang LMP, maraming factors like irregular cycles na nakakaapekto, so don't worry too much. A few of us din dito sa grupo nag-experience ng similar discrepancy at ang doctor namin always go with the ultrasound date as more reliable since it's based sa actual baby measurements. Best to chat with your OB kung saan siya mag-count from para sigurado lang kayo both, pero honestly, you're almost there na regardless!
