First ultra sound bleeding..

I went in Friday (3/15) for my first ultrasound. I finally got to see my little bean, and its heart beat (134) measuring 7 weeks. The US tech said I had some blood behind my uterus most likely from implantation and it really was no big deal but to expect some old blood to come out. Also at that appointment she didnt do a pap, but I'm pretty sure checked my cervix? And said to expect some spotting. Saturday rolled around and it started with a little bloody discharge. I wouldnt say it was bright red blood, but not brown either (about the size of a nickle). Since then Sunday morning & this morning with my FMU it's almost tinged red. All the discharge is a tan/brown color so I know it's old blood but why Is my urine like a bright peachy red color? No clots or anything. Anyways.. has anyone experienced this after an exam and did it turn out to be okay? Please help ease a paranoid first time moms mind here!

*anything helps*!!
