I was told I miscarried on Christmas Eve

I was told I had a miscarriage on Christmas eve and on top of that my fiancé’s Birthday....I went to the ER and the ER doctor couldn’t tell me anything concrete and said she only can see a yolk sac....however, I only bled (bright red) for about 3 hours and a clot and then it stopped by 3 that evening. I was put on bedrest for 2 days.

Fast forward....went back on this past Friday to have levels checked and was sent to ultrasound and I will have my reading for that and following up with my HCG levels on January 2nd. I still feel pregnant and also considering I passed a clot has me doubting that I’m still pregnant. This is the test I took earlier today and the test line is darker, not lighter as if I’ve miscarried and my breast are still sore. So much anxiety and over thinking. I pray for the best and Happy New Year mamas and mamas to be.
