Pregnant or no??

So AF is due tomorrow. No symptoms of her arriving at all today . My boobs are sore but not outrageous. I’m hot, cranky, I have a headache....oh and I woke up to what feels like a pinched nerve in my lower back. I tested this morning with two pink dye tests and both were negative. I took a blue dye yesterday and it was very faint but positive.

Could I still be pregnant with two tests this morning being negative this close to AF? I’m going to test in the morning and I’m keeping my fingers crossed.
