Has anyone experienced this?

I had a normal period in August. Had sex on my highest chance day during ovulation. I'm 11dpo now and keep getting faint lines on my tests almost immediately. All blue dye. My store is always out of pink dye tests. I had been having wierd cramps on 6dpo and 7dpo as well as sore boobs those two days and nausea all week except today. I feel like maybe I was just psyching myself out because I was excited? Did anyone get faint positives 7dpo-12dpo with a blue dye test who was actually pregnant? Did you have the same symptoms as me?
