I got my blood drawn on October 9 when I was 4w5d, and it was at 1330. I had them drawn last night, at 6w1d, and they rose to 30,000. I did the calculation and the doubling rate is 52 hours. Does that sound good? I had a miscarriage in June, so now I'm terrified of anything going wrong with my baby. I have an OB appointment next Friday, and I have no idea if I'll get an ultrasound or not. Does anyone have any insight? Do my levels sound good for 6w1d?
