10d2d spotting

Hello,

So I’m 10w2d and yesterday I had small amount of red spotting when I wiped and mild cramping. Today I had a small amount of brown when I whipped. It was all only when i wiped. I’m worried I’m miscarrying. I talked to the doctor she was kind of worried so I went to emerg they did blood work and told me they’d cal me to come back today for ultra sound but I haven’t heard anything from them yet today. Has anyone had this happen to them? I’m so worried as I’ve miscarried before (blighted ovum). This baby has had a heart beat at both ultra sounds so far and everything else has looked good and my cervix was closed as of yesterday.
