TTC is driving me CRAZY!!!

I know you have been patiently waiting all day....or maybe you have been dying to know.....or maybe you could care less....but the results are IN! (Well, sort of....) When Brad and I were grocery shopping last night (after we witnessed a truck have a wreck with a motorcycle, the truck running OVER the man on the motorcycle, the man being flung into the median of a very busy highway, waiting for the police and ambulance to get there and giving a statement of what we saw to the police) I decided that I was TIRED of always buying the expensive pregnancy tests. I've heard the cheap ones work just as well as the expensive ones. So I bought Fact Plus. Cheapo. Then this morning, I got up and took the test (how many times have I done this now!?). I brushed my teeth and looked down (not expecting to see anything) and I saw a faint line! I picked up the test to get a better look and the line disappeared a little. Crap. I wasn't supposed to touch it for like 2-3 more minutes. The line was sooooo faint, it looked like a little piece of thread was on the screen. I woke Brad up and told him to look at it. He said that he didn't see it (but then again he was still half asleep and his eyes were not focused yet...). So I brought it to work to let my sister and Mom look at it. Mom couldn't see the line, but April could. Did I mention the line was FAAAAAAAAAAAAAAAINT?!?!?!? They keep telling me "A line is a line" but I'm just scared that because it was so faint, that it might be a faulty test, or a false positive. Usually if the vertical line of the (+) is faint, it's the whole line that's faint, right? Mine only showed a little thread of the vertical line. So we went out and bought an EPT Certainty Digital test. Negative. BUT my urine was less concentrated (at 10:30am) and the digital test detects hcg as low as 50.....the cheap test detects hcg as low as 25. So maybe I'm just barely pregnant? Like Las Vegas pregnant? And so my hcg level isn't higher than 50 yet? I'm so confused. And at this point, I've probably confused you too. SO I'm just going to take the other cheapo test in the morning and hope and PRAY it's positive too. PLEEEEEEEEEEEEEASE pray that it is!!
