I miscarried December 25th, my levels were only 72, the next day they dropped to 20. It's been a month now, and I just ha d a feeling so I took a test two days ago. the line was so faint, and almost invisible to the eye. I retested today and the line has darkened some. is there a chance this is left over hormones? Or is it my rainbow baby?
