Has anyone ever had their period keep coming while pregnant without there being anything wrong with the baby & then eventually delivered a healthy baby?

I'm 8w2d & I had bleeding about a month ago that was consistent with like a medium flow period with small clots and everything but we checked on baby and they were okay and all my hormone levels seem normal. Now I'm having bleeding again which is like a medium flow period with the small clots. I called my OB as soon as I started bleeding and I got an ultrasound the same day and baby looked like they were growing fine and had a heartbeat still. This is my fourth pregnancy and I've never had anything like this before and it's almost like I'm just getting my period still even though I'm pregnant?

Has anyone had a similar experience? What was the outcome?
