I'm so confused

Autumn • My boyfriend and I been together 9 years this Aug. Mothers Day 2016 I found out I'm pregnant .
Can someone explain why my hug level is 5070044? I don't know what the hell is going on unless the nurse wrote too many numbers. On the same day my ultrasound they couldn't see the baby and I have to get another one done. I'm 7 weeks today and my levels are still rising I don't know what to think at this point. Seriously if anyone has any clue what is going on w my body lol please let me know
