us- week 8

My name is Idit and I am35 years old.This is my third pregnancy after fertility treatment. In my 7 week I did US. there was no heart beet and there was blood in my uterus. In the US today (8 week) we found that the area with the blood got smaller, the pregnancy sack got bigger and we could see a small heart beet that the doctor think is mine. Can the heart beet be mine? Is threr a chance to see better results next week? Thank You Idit USA

המתיני בסבלנות ייתכן שההריון תקין לחלוטין
