We need all the prayers we can get. Pregnancy related

I had an ultrasound Monday at 5 weeks 1 day. It showed a sac in my uterus, but a little low. I then had HCG hormone levels done today and they were lower than they should be. They should have been atleast 360 and they were 160. Which was odd in itself, American Pregnancy Ass says that you can't see anything unless the levels are 1000. We have another ultrasound on Saturday. I ask for all the prayers we can get that this baby is a sticky and take home baby! Please pray for us and our baby.
