Blue line tests are notorious for evaps that look like blue lines, combine that with taking a part a test...I hate to say it, but all the tests become invalid at that point. Although I do see some blue line progression, it wouldn't be right to speculate based on that.

To have a better idea of what is going on, I suggest using pink line tests and avoid opening them, which can definitely impact what you're seeing. A blood test is the only way to know if hcg is doubling as it should.
