Feeling strange

I feel pregnant. I've had a strobg sense of smell. I feel bloated. Feeling wetter down there. Nausea. Tired alot. Mild cramping. I believe I ovulated about the 22nd-23rd of feb but according to glow I didn't ovulate till like a week later. I have taken a few tests all negative. I have been using the cheap tests I bought from Amazon could it be that those could give false negatives? Is it just to early? Am I out this month? I want to be pregnant so bad. AF is due soon I usually get premenstrual cramps and mild spotting right before but my cramps don't feel like usual cramps and I have not spotted a single drop if blood.
