Just seen both of your threads.
I can definitely see a very faint line on all 3 but if you've been pregnant for 2 missed periods you should have a much, much stronger positive.
Is it possible at all that you had a lighter period last month and conceived this month? I'd pop to the GP and explain the 2 months missed and faint positives. Hopefully they will test your bloods and have a look at your HCG levels to see what's going on.
