Low HGC levels.

So we took a test and it was a faint line. Did a blood test at 4 weeks and my levels were at 25. Did one 4 days later and they were only 65. That was yesterday and my OB wants another blood test this Thursday. Also started progesterone yesterday 3x a day.

Had anyone else experienced these low levels before?? We lost a baby in Feb. @18w. So we are really hoping this baby stays put, but these numbers get me nervous.
