Hcg beta level=605.65miu/ml, progesterone=23.65ng/ml lmp=13jan, 1o day overdue. Is this normal? Too worried hCG is too low according to charts available

Trend is important. You should focus less on the tables and more on the pattern. The beta levels should at least double every three days. Your doctor will probably want to do an ultrasound when your beta reaches 2000 or so. The Progesterone is fine.
