I'd recommend getting a digital test as they leave nothing to doubt. I got a couple of faint positives with the dip kind but the second one done about a week after my AF was due came up fainter than the first one.... both took a while to come up but were within the recommended guidelines. I panicked and went and got the digital one which supposedly needed higher concentrations of HCG to show a positive and I got a BFP really quickly which calmed me down again.

I would also recommend not to get too excited until you get results from a blood test.
