Hcg and progesterone levels

Rocio
Hi guys! So I got my Hcg level tested on 15dpo and they were 784 and today 18dpo my Hcg is 1839 and my progesterone at 21.2 
According to the app I'm 4wks and 3 days (due 9/8/16 so far) 
Are those number too high? should I be concern? I'm being paranoid. This is my 1st pregnancy after 2 years trying to conceive so I'm still in disbelieve (keep peeing on the stick everyday just to calm my nerves ... Yeap that type of psico ... :/ )
I've been cramping on and off and sometimes I get sharp, stabbing pains on my left and right side ...  
please share your numbers!
Let's hope "tomato seed" sticks
