Advice on pregnancy testing please!

So the day I got a positive hpt, I went to get a blood test. My blood test was negative, a level 2. Since then, two days ago I have still been testing positive on hpts. 
This happened to me before, and now I have a beautiful 4 month old. But last time I waited 5 days to redo the blood test, came up positive at 194. 
Should I redo my blood test tomorrow, 3 days after a negative blood test? Or wait longer? 
I know I'm pregnant but I don't want to look crazy if it is too soon and still comes out negative
