Yes. I was told (second pregnancy didn't have an SCH with my first) I had one at a 9-week ultrasound. Never had any bleeding. Currently 37+ weeks. They weren't concerned. It must have cleared up before my 20 week ultrasound because I never heard anything else about it.
I had on in my first pregnancy. It felt really scary because I was spotting which is why they found it but it cleared up on it’s own and it was totally fine. They are fairly common as well so I would say if your dr is not concerned at all you are just fine
