Line Progression- After Chemical

Looking for some guidance and reassurance as I definitely have some stress going into AF week with a chemical pregnancy last cycle. I know typically hcg takes 2-3 days to double and I don’t have blood tests ordered by my doctor but does this seem like a normal progression. Of course I’m having some mild cramps and sore breasts making me even more nervous AF is coming. I think the 5:35 sample in the afternoon was diluted from my water drinking and not a long hold. Anyone been through this before?? #ttcin30s
