How common is it?

Hello,

I just found out I’m expecting again after and early 4.5wk chemical pregnancy last month. I stumbled across this term called a blighted ovum. I’ve never heard of it before and I’m curious to know how common it is for women. I’m worried that this will happen to me for some reason.

Also, I will be 4 wks on Friday and I have no symptoms… occasionally some light nausea that’s what made me test in the first place.

With my daughter who is now 5yrs old I didn’t find out I was pregnant with her till I was 7wks along had no symptoms what so ever until 7wks

Then with my son I had nausea 3 days before my missed cycle and I had non stop nausea with him up to 16wks along.
