HCG levels

Neshia💙👣💖 • 23, soon to be married. TTC ( 1 yr & 7mo ) , my fiance is the best 😘😍 couldnt ask for some one better. "Im just a woman, trying to be a mom & start a family " 👪👶👣💙💖
Okay- so I've recently found out I was pregnant. And my HCG levels when i found out 2 days ago was only 50- I'm not sure what it is now.  I'm only 1-2 weeks. I guess I'm just confused, according to glow- I'm 4wks 3days... 
I'm not really sure about all of this how I count, what I do- any advice?
