Panicked FTM, Pls advise

Hi mommas

It’s my first time being pregnant, other than a chemical last month. I’m almost 5 weeks. Doc saw beginning of yoke sac today and said she saw everything she expected to see. Everhthing I’m reading is making me panicked about habit a blighted Ovum. It seems like such heartbreak after such joy, and I already experienced something similar last month.

Is there any way to predict if you’ll have one? Any way to predict if it’s likely? What would I be experiencing or not experiencing or seeing or not seeing at this point if I was going to have one?
