Hi, there are only two days that I could have possibly conceived and that is 14 weeks ago and the other is approximately 3.5 weeks ago, I recently took a beta HCG blood test and received a result of 1 IU/ml, I was wondering if there is any possible way to be pregnant with that result and if not then is it normal for none pregnant women to have HCG in there blood stream? Why do some and some do not? Thanks
