2 days late

I have a few different apps and i have two different start dates. On this app i am 2 days late, and on my premom app my period is suppose to start tomorrow. I took a few test in the last few days and i had very faint lines on some cheap test. Yesterday i decided to buy one but they only had blue dye available and I saw a very faint line. Today i got a pink dye test it was one of the cheap $1 test and I really didn't see anything on that test. Should i wait till i get a totally missed period or should i test in a few days. Below are the pictures of the test i took yesterdayy
