Light blood after pelvic exam

Blanka
I had a pelvic exam & vaginal ultrasound Tuesday at 10am, I am around 5 weeks pregnant... Yesterday when I went pee and cleaned myself it was a light spot of blood, the rest of the day I was fine then today in the morning when I went pee I had another little light spot of blood and right now again... I am not feeling any pain, should I be concerned? I have my next appointment in two weeks from now... everything was OK until they stuck those plastics and fingers inside me :-( ... I did see the baby sac and yolk ...
