Could this be....?

a period?????

Miscarried 10/28 and have been doing weekly blood draws (24,000 while pregnant, 495, 40, and 10 last week with one more scheduled this Wednesday).

But, I have been saying to doctors for a week that I feel like I'm cramping, like PMS.  They keep looking at me smiling, but saying it IS possible, but dear, it probably is not. However; my numbers crashed after miscarriage and they do say anything is possible since they havent seen that often that numbers return so fast.  soo.....This morning, I am spotting lightly a brownish color and still getting PMS like feeeling and cramps.  I was told 20 days of not bleeding will count as a period.  3+18 = 21 days post miscarriage.  

Could this be it....will it start?????  Whooppee!!!!!!!!!!!!!!!!!!!!
