Help very light positive!

Tasha
I need some advice. I have been getting sick at night. (Ex: horrible heartburn, body cramps, nausea, headaches, and hot flashes). Everything goes away by 7am. I took a test Thursday morning came back positive (clear blue early response). Thought I would wait and take another closer to missed period (today) still see a line but its lighter then before. Am I getting false positives or has it just gone away. Any advice is welcome. Feeling aslone
