Too soon or getting my hopes up, again??

My husband and I have been trying to conceive for the last (almost) 5 years, but we have been unable to get pregnant. We've taken Clomid before, and nothing... They've ran multiple tests on him and me, and they all come back clear. They don't know why we're having such a hard time. I've been experiencing some pregnancy symptoms such as, sore breasts, dizziness, slight nausea, some moodiness, and some cramping, so I took a blue dye test Sunday morning. It had a vvvfp, so I re-took one the next morning with first morning urine. It was a digital. It said not pregnant, but I was told that they're not as sensitive. So I got a Walmart cheapie that has purple dye and tested today. I didn't see a positive line. I'm 11 DPO, and I'm 3 days overdue for AF. If I am pregnant would a test pick up my levels, or would it be too soon? Do I need to wait another week or so? Help please!!!
