Early pregnancy spotting SOS 💔

I am 5 weeks 4 days and have been spotting for 5 days. It is only when I wipe and is between pink or brown. This morning it was more than usual it was dark pink almost red. I had an ultrasound yesterday and there is no bleeding in my uterus. The bleeding is coming from my cervix. My doctor did not do a pelvic exam or take blood work. He wants to see me again Friday to see baby's heartbeat. Then he said he will do blood work. He's calling my pregnancy a threatened miscarriage. The ultrasound tech said my spotting was likely due to changes in my cervix and all the new hormones. But that doesn't stop me from being so scared I'll lose the baby. I find the spotting becomes pink when I bear down like have a bowel movement. Or if something is inserted in my vagina. Or if I cough too hard. Has anyone had this experience and went on with a healthy pregnancy?
