Hello, ultrasound showed 6 weeks. Ultrasound diagnosis was inconclusive pregnancy at an early stage. They said to come back in two weeks. After the ultrasound, I went and took blood test for hCG 605.2. Before the ultrasound, the test had a weak line, now it's bright. Has anyone experienced this? Is everything okay? The ultrasound diagnosis is confusing me.
