these test

Hey guys so I've been pooping pregnancy test for 4 days before my period and they have all been positive. my period was due today. but everything else is turning up dark. anyways my question is, do the easy at home test show dark also or very faint looking no matter what. cause I took one this morning and it was super faint but the rest have been dark. And I've been getting the pregnant results in digital also! does this mean I'm possibly could be miscasrying care my hcg inst getting darker on the lines or what!!! Or is that how those home at easy test are???? this was this morning
