VVFLS!

I have tested a few days now and every time there are vvfls, that show up well within the alloted time to check the test. They have all been very very faint. I am not sure, but I dont believe I have not missed my period yet. (The birth control i was on before really messed up my cycle.) But I have had several bouts of unprotected sex..

So my question is: If I have taken three tests (of different brands) over three days and they all have very faint lines, within the readable time frame, does that mean I am probably pregnant? Two of the lines were more promonent than the others but faint nonetheless. I know, keep testing. And I will. I just wanted some sort of answers!!

Side note: All tests were a mixture of pink/blue dye.
