I just got my third blood test back and I am alittle worried that it is high. I have been reading websites about twin hcg levels and molar pregnancy, and have now freaked myself out. Here is the history I should be at 5 weeks and 1 day my LMP was on July 9th. The first test was done on aug 3 and came back at 198 my second test was taken on aug 7th and came back at 1398 and now a week later on aug 14th 19998. Please help set my mind at ease I go for my first ultrasound on monday.
