:'( someone please help

I'm not exactly sure when I ovulated, I just "guessed" a day by keeping track of my cm and cramps, and because of that my days past ovulation count can't be accurate. All my test are so faint not getting darker, I've been crying all day. I don't know if I'm really early or having a chemical and I can't go to my Dr because if my lines are faint like this then they surely won't be able to detect anything! I'm so upset!
