Confused! Advice please

Has anyone gotten a faint pregnancy test right after their period? My period was pretty much over on Monday minus some spotting. It was shorter than normal but not any lighter than it usually is. But I had NO cramping which hasn't happened since I was probably 14. They're usually excruciating. Anyway so this is my first month testing for ovulation. Both yesterday and today were my first days testing and they were both dark but not as dark as control. Randomly today I decided to take a pregnancy test too, and I swear there was a SUPER faint line. I mean I've never even had any bit of a second line before and I don't kid myself when I know it's negative. Has this ever happened to anyone before? I mean if this line I saw is true, wouldn't it be too soon to be pregnant?
