Any mummies had subchorionic space during their pregnancy?

Hi mummies! Im now 10 wks and 5 days, had the ultrasound scan yesterday and they found that I have a subchorionic space. Anyone of you experienced the same? I haven’t had any bleeding or spotting of sorts. I also read up that this will clear up on its own in a few weeks. The dr told me there’s nothing to worry about, everything looks good but hey of course im worried haha. 😂 #firsttimemama
