Can’t tell anymore..

So I posted yesterday what I thought were faint lines.. a few people agreed. After a miscarriage feb 20, I don’t want to get my hopes up. Well I took a digital test today and it said not pregnant. Then I took a clearblue test and I can’t tell if there’s a line. After I took two of the dollar store brand tests and there’s faint lines.... I’m so confused now. First positives then 2 negatives and then 2 more positives.... any clue what you guys might think is going on???? The two tests below are the last two I took where I think I see faint lines...test 3 was the digital not pregnant test
