Hcg 4-5 days past AF

Ella

Here is a picture of my pregnancy tests starting from Sunday 23rd, 2 on the 24th and one today the 25th. I had blood work done yesterday ( which it would have been 4-5 days of missed period) and my results came today. They were 309. I've seen many women with over a 1,000 by now so I'm not sure if it's too low? Even though I read that is in the normal range. Thank you in advance ladies!
