What are the chances of 4-5 faint lines on one brand and not being pregnant?

I've tested with dollar tree tests - negative, FRER - negative, and clear blue - 2 negative 4 positive but with the lightest lines ive ever seen! I'm really hoping they get darker, I do feel pregnant but I just wish I had hard evidence... what do you think the chances are that I'm not pregnant? I'll post pics of the tests...2 were done at night, two the next mornin

Thank you all for your support! I am going to do my best this cycle not to test until after I miss my period...as if I have any self control haha, we will see. Strangely, I'm kind of relieved, I really just wanted an answer and even though it's not the one I was hoping for we do get some more time to try... I ovulated early and we tried to do things to concieve a girl so...hopeful!
