EQAUTE brand test*

on the 6th I swear I had implantation bleeding so the next day in the evening I took a test(labeled 1st) and I didn't see the line at first so I put it aside and the next morning I tested again (labeled 2nd) and I saw the blue line! So I looked at the test from the evening before and saw a lighter blue line then that one that I just took so here I am thinking I could possibly be pregnant after three years of ttc and took a digital test the next two days after both stating not pregnant. Then took a 3rd test this morning and I received another faint blue line but still darker than the first one. I looked up this brand and read there's false positives you can get with them and blue dye test so idk what's up. I've never ever had even the faintest of a positive line with in the 3 years so I'm going to be so heart broken if this is a cruel dye haux. The 2nd test is definitely darker then the first one but I took a handful of the cheap test strips and two 88cent Walmart test all looking negative. I'm praying it's just too early for a dark line and in a week I will get my bfp for sure but what do you guys think?
