Please help!

How faint can a positive line be? I have two test that I’ve taken and took it and let them sit(didn’t check right away because if I am I am going to surprise my husband). But I had two friends look and they think they also see the lines. I keep looking and I’m just getting frustrated because I can’t honestly tell. But I can’t even get a good picture of what I am seeing. The test are taken a day apart. I’m just wondering how faint can the lines be? I am blind, so maybe I’m just seeing things to😩

My period is supposed to be starting in to weeks(it’s been all messed up) and my boobs are itchy and started leaking, which hasn’t happened since I stopped breastfeeding my son.

Please help. What do you see?
