Isn't it too early?

Okay so, according to when I believe I ovulated if only be about 4 DPO... But I'm Naseated on and off, been really bad last night and this morning, hot flashes, I mean it's snowing weather and I have the heat off and wearing a sleeveless top like it's summer outside, some light cramps, mostly just feel really bloated, a bit of a stuffy nose, I'm tired and started peeing a lot since last night too. I know it's still SUPER early but, I took a test yesterday afternoon and I swear, a really faint line. Took one with FMU this morning and that line seems to be getting a little darker... Are these just Evaps that have gotten darker or could this really be the start of our BFP?
