BFP at DPO12??

Hello

I took a Clearblue Digital test first thing this morning and got Not Pregnant - I had a few twinges in my stomach last night but thought I may be testing too early.

I just tested with First Response which I believe is more sensitive - does this look like a second line please?! I want to wait until hubby is back from work but not sure if the test is reliable if you leave it for a few hours!

Thanks xxxx
