6 weeks...miscarriage?

I started brown spotting day before yesterday. My midwife got me in this morning for my first ultrasound. It was a bit painful by the way. Each day I’ve had a bit heavier spotting. It was much worse after the ultrasound although everything seemed fine and I got to the the babies heart beat. First pic was from an hour or so ago no sent it to my midwife and she’s concerned and I go back in the morning at 9:30 for another US. The second pic is now. I’m soaking in the bath now and pulled out some substance. Thoughts?
