First HCG level

My first HCG level done yesterday was 95. I am only 4 weeks, so that is within the normal range. I can't help but want it to be higher. It's supposed to double every two days. However, I am unable to have another one done tomorrow. I am scheduled to have on done again Thursday instead. BUT....being a nurse can sometimes have its benefits (and downfalls). I had one done today at work and my level came back as 130. So, it is working it's way to being double!
