Mama, please see your OB right away, today if possible, para ma-check properly ang situation mo. Ang placement ng gestational sac ay importante at kailangan ng expert ultrasound para sure, hindi lang guesswork. I know this is scary, lalo na after your MC last year. Maraming mum friends ko ang napassed through similar worries, at ang best thing talaga is to get proper monitoring from your doctor, they can do follow-up scans and give you real answers based on what they see. Stay strong, ha. You're doing the right thing by checking.
