Anak, I know this is really scary and confusing with the different findings, please see another doctor today or tomorrow for that second opinion, it's so important for you.
A few of us mums have been through confusing ultrasound results early on, and honestly, getting a second opinion right away is the best thing you can do, different machines, different doctors, sometimes it makes a difference. Wag kang mag-atubili to go to the emergency room or call your OB now if you have severe pain or heavy bleeding, okay? Rooting for you, and I hope the next scan brings clearer answers. Keep us posted.
