Spotting and bleeding in 5 weeks

Im currently in my 5th week. I got my check up sa OB yesterday and requested for ultrasound since nag spotting ako ng brownish na blood. And then today, just this morning may lumabas po na clot of blood not as much as my period and I am not feeling pain or crumping nmn sa lower abdomen. May naka experience na po ba sa inyo ng ganito? I am still monitoring po about this, pag umiihi ako sumasabay yung blood.
