Pregnant?

The first day of my last period was July 16th. I took a pregnant test 3 days ago and was negative (cheap wondfo brand) I took one tonight and just set it down and walked away because I figured it would be negative anyways. I came back an hour late and there was 2 pink lines (1 faint) so I took another one and waiting the 5 minutes and got this. This was not FMU either. I am so torn because I will have to wait until tomorrow to go by a better test because these are prone to evap lines! I really pray it is positive because today is my daughter birthday (she passed away in 2009 at 17 days old) it would mean so much to me! And I can't tell hubby until I'm sure because he will be so excited!!!
