have first miscarriage before

Hay, I understand your fear kasi na-experience mo na yan before, anembryonic pregnancy is really heartbreaking talaga, pero 5 weeks and 6 days is still super early pa, kaya hindi pa talaga makikita ng malinaw ang embryo sa ultrasound nang ganyan ka-maliit pa lang. What I'd suggest is follow up with your OB in a week or two para makita na talaga kung may development, kasi sometimes ang dating unclear at 5-6 weeks is normal pa, mas malinaw at mas reassuring ang sumusunod na ultrasound, so don't lose hope just yet. Fingers crossed for you, and please do touch base with your doctor soon para ma-address ang worries mo properly at ma-monitor closely ang pregnancy, lalo na dahil may history ka na. You got this, mama!
