Please help 10 w and spotting

Hi so I am currently 10w 4 days I had a scare at 8 w with a subchronic heamorage 3cm in size I was told it was a threatened miscarriage. I went to have an ultrasound done privately and I measured 9w 3 days the doc told me the bleed went from a size 3cm to 1cm and baby is doing great with a strong hr. Now I'm 10w 4 days I'm still spotting brown one minute it's coming dark next it's coming light colored, but not red. No pain or anything. Hubby and I did have sex about 6 days ago when it was very light brown. After that I noticed the brown spotting increased and until now it's still enough to have me worried. Is this normal? I've just read about missed miscarriage and I am so paranoid about it. My anxiety levels are so high right now I'm just so terrified. Has anyone been through this and ended up okay? 😔😔
