TTC problems!

Okay, so I'm literally at a stand still. Tired of the same thing, and disappointment each month. So to catch up with anyone reading this I'm on cycle day 58...6/17/17 was the the first day of my last period. My cycle range is from about 30-35 days. I've literally taken so many test and all of them come up negative, but then a couple hours later I'll look at the test and there will be a faint line, not like a evap line, these lines are thicker with a little color. And all the ones I've taken have done this at some point, but every week the "faint lines" I'm seeing don't get thicker, just the same as the others. Usually the last couple of months complete negatives, no faint positives, or evaps...except this month. My other problem is I'm SO bloated, I keep getting little pinch's in the right side of my stomach, tired all the time, and wake up feeling like all my muscles are hurting, and towards the end of June I spotted which looked just like implantation bleeding (which I had with my first baby) ...so I thought no, I'm just getting my period but nothing ever happened. I've been waking up each day just waiting for Af to be like "surprise" but I get nothing. Still hoping I'm pregnant and I'll get a positive! My friend keeps telling me I should get a blood test, but I want to wait a bit longer and see if my period will come this month. So with the with that being said here's my questions that someone could help with

*Has anyone ever got a positive late in their pregnancy? If so how far along were you?

*Or maybe missed their period but still getting negative test?
