hcg levels/doubling time

hi ladies!! i know many people don't put too much thought into hcg levels, just as long as they're rising and doubling.  I just wanted to see what levels people have been having. at 4w2d my level was 977, yesterday at 5w2d it was 15,879!! my doubling time is 44 hours. does this seem high? I'm certain of my ovulation date, too. thanks xoxo
