I need help!!!! Please no judging!!

And before we get into it I just want to let y'all know, my DH and I have been trying to conceive for 3+ years. I am a poas addict, still haha! I read the directions on the box and follow them fully....except this one time. 

Okay so Monday (3/20) felt some weird cramping and bloating and lower back pain. Just chalked it up to pms symptoms cause af was due in 7 days. Went and got some cheapie pregnancy test just to rule out a possible pregnancy. Took one when I got home and it was a negative. So immediately threw it in the trash. Thought nothing of it.......until today.

So today, Wednesday (3/22), got home and was weirdly nauseated. Thought it was just the heat getting to me cause I live in LA and it's like  80-90 degrees. Never had a positive test before. Thought "hmm, I wonder what a test looks like when you let it go past the time limit." So I dig it out of the trash, yes gross I know. Looked and there was a faint line. I mean I saw it. I'm not thinking anything of it cause I mean you know it's like 2 days later lol. But idk like I'm lost. Take another test? Just wait it out??? I have a pic of the test cause it's just silly to see what a positive test looks like. So yeah if y'all ladies could help me I would really appreciate it.
