Blood clots while bathing

Im 6 weeks. And i was bathing when blood clot like the image came out. No feeling at all. I saw it on floor after i finish bathing. A day ago i just at urgent o&g due to bright red bleeding. But doc checked.. cervix is closed. No active bleeding. But there are blood residue inside. And baby heartbeat doing well too. Any idea why will such clots suddenly be passed out? Anyone have same experience? #advicepls
