Ultrasound in 8th week shows yolk sac, also shows echos of bleed. Why does this happen and any risks ?

Hello, I have had 3 ultrasound scans now. I am 8 weeks pregnant only on the last scan at 8 weeks a yolk sac became present. This was not there in previous scans. I also have an irregular pregnacy sac showing echos of a bleed within. Next scan is on Tuesday. Do you have any idea why this would happen or if this pregnancy will be successful? Thank you

thanks for your query.
By 8 weeks, if your periods have been regular, a proper yolk sac and embryo with heartbeat should be visualized.
Also, if the gestational sac is more than 20 mm, without an embryo being seen, then the pregnancy is a failed ( non viable ) one.
Causes can range from genetic causes, to infections, to hormonal imbalance, auto immune causes, as well as trauma, radiation, teratogenic drugs etc.
I think the prognosis for this pregnancy is not good, and the next scan would confirm this.
Take care.
