Bleeding during first trimester 😳

Teri
I am 10 weeks and this morning I woke up and I had some light spotting. Every time I went to the restroom I was spotting but it was pink . The last time I just went it was a little heavier and it was red . I am not having any pain in my stomach or abdomen but I am bleeding . My doctor has schedule an ultrasound for tomorrow but I am so scared and nervous . Has anyone else experienced this ?? If so what do I do ??
