ER Scare

We had a scare 3 days ago. After light spotting on and off for a couple weeks, I suddenly had clots and bright red blood. Terrified, we went to the ER, had blood drawn and an ultrasound. After long hours in the hospital and convinced the worst had happened, I can't explain the relief when we saw the little heart pit pattering away! I found out that I'm 6 weeks & not 8. I can't help but still feel that we are not out of woods yet. Just yesterday my new insurance plan started and it's nearly impossible to get an asap appt. with Kaiser just to follow up and make sure everything is okay! I'm wondering if I should go to urgent care since I am still spotting slightly???
