Any thoughts ??

Okay so I am 5 weeks and 4 days today and I had light vaginal bleeding which is the top picture, so me not knowing what it could possibly be and its my first pregnancy I am scared and went to the ER they said it could be a possible miscarriage but I am not having any pain at all NONE and the bottom picture is what it looked like after I left the hospital I went pee and wiped and there is no sign of blood what could this possibly mean ??
