Please help - what do you think?

So sat I was really nauseous and kept dry heaving - threw up stomach bile once and thought oh great i have the stomach flu so i went home early from work and sleep basically all day waiting for the flu to set in but it never did. Yesterday i was a little nauseous and couldn't really easy anything but peanut butter toast and today I am really really nauseous. Im supposed to start AF tomorrow but I have no symptoms at all. I have had crazy heartburn too which is unusual. Could I be pregnant? Would the nausea have set in this early or am I just hoping to much and setting myself up for disappointment again?

I did take a cheapie test yesterday in the middle of the day but didn't see anything right away so I figured it was neg and threw it away because I had to deal with my 3 year old.

We have been ttc for almost a year and i swore I wouldn't get my hopes up anymore because it breaks my heart everytime AF shows up. But I can't get the thought out of my head with this nausea.

What do you ladies think? Anyone else in the same boat or was and found out they were preggo?

***update***

So I was supposed to start on the 5th and still haven't. I tested on the 4th 6th and 8th with cheapies and they were all negative but still no AF. I have had terrible nausea heartburn and extreme fatigue and tiredness. I dont know what to think
