Missed MC???

Ampy
I'm hoping for some success stories but am open to hearing anyone's experiences. I should be 7wks tomorrow based off my LMP. The day after I got my BFP I started spotting for a week. It wasn't heavy like a period but started off scant and pink then moved to red but still not crazy heavy like AF. I went to an urgent care and my HCG level tested at 62. The doc told me I am having a threatened MC. I followed up with my OB 5 days later and my level was 38. She said I am most likely miscarrying. I was thinking maybe I already had during that week of spotting and my HCG level was just going down. Went back 6 days later for labs and my HCG went up to 45. 3 days later it was 54. And my latest was 4 days after that and is now 60. They have me going in for another draw tomorrow which is 3 days from my last draw. I also go meet with the doctor Friday to discuss medical management. The nurse said I could be having an ectopic pregnancy or missed MC. She's leaning towards the missed MC and said that usually in ectopic the numbers rise quicker. I am holding onto hope that maybe I am in the 15% whose HCG numbers just don't double as the should. I know that since I should be 7 weeks my numbers are EXTREMELY low and out of the low range but was looking for any advice or stories.
