Early scan

Kadie

Hi ladies. I went to early pregnancy unit for scan. I was supposed to be 5 weeks today according to my lmp. After the scan they told me that the fundal aspect of the endometrial cavity contained irregular sac like structure, measuring 11.6×6.9×8.6 mm( mGs= 8.6 mm). No yolk sac or fetal pole were seen? Gestation sac? Pseudo sac. Please ladies help me understand what going on. Am I too early or am going to have miscarriage? I have no bleeding or any symptoms.
