Worried

I've had multiple miscarriages this year. And I finally got pregnant again after 6 months. Well Monday they took my blood and Tuesday it was 17 hcg, went back in on Wednesday for hcg and polgestone or whatever that word is called to see if my blood line is thin to hold a baby they called me this morning to tell me hcg is at 16 and the other blood work was 1.6 and wanted me to come back next Wednesday for same test to see what it does. So to mention it dropped down just to 16 from 17 starting a Monday. I am bleeding, im not cramping still having symptoms of being pregnant. So at this point I really would like honest advice of what I'm going to look forward to. Cause unfortunately waiting till next Wednesday to do more blood is scaring to know what them numbers are.
