When should I test??

This is my husband and my 2nd month TTC. AF is due on Thursday, but I'm hoping she doesn't show up! I told myself to wait until Thursday to test, but I don't know if I can wait that long haha I want to test with fmu tomorrow, but then again, I think I need to wait. What would you do?? I'm trying not to get my hopes up, but I feel like this month is the month, so I want to see the BFP ASAP!!!
