I have been doing some googling (I know I shouldnt) as I had 4 miscarriages in 2015 . I am 7 weeks pregnant and my hcg levels were doubling about every 3 days and the last test I had it took about 5 and a half days to double . I read after the hcg is 6000 it is normal for it to take longer then 96 hours but I can't help but cry and feel scared something is wrong .
