Ate, this is really something na kailangan mo talaga i-confirm with your OB-GYN as soon as possible, hindi ito dapat ma-delay. The difference between LMP dating at ultrasound findings, especially with the sac appearance, needs proper medical assessment kasi only your doctor can tell what's really happening. I know maraming amin na friends na nag-try ng different supplements, pero honestly, this situation is beyond what supplements can address, your doctor needs to see you in person. Praying for you, sis.
