Help!!!!

Ive been having pregnancy symptoms this past week. Nausea, sore nipples, headaches, cravings like wochesgire sauce, canada dry ginger ale (only this brand the others taste gross to me when all gingerale was nasty prior to now), shrimp dip, pizza, and soft tacos. Today i am 11 dpo and 5 days til af. I couldnt wait so i took a pregnancy test. And it came up faint pos within 60 seconds. Then the control line got darker the test line got lighter. It was barely there at all by 3 mins. Then it was just a shadow of a line but still had color. Is the test invalid? I only had one test. It was pink dye.
