HCG progression Help

So I could be over thinking but I got my HCG done last Thursday and results came back at 17mi as I was only 13dpo. Yesterday I had more blood work done which is three days since my last blood work and puts me at 16dpo and the results only came back at 88mi................. I am feeling like this isn’t a good progression and has me stressed out. I’ve been pregnant two other times and always had great progression but this one just doesn’t seem normal. Am I over reacting? What do you all think. I keep taking tests and the line keeps getting darker so it’s still adding up. Thank you in advance!
