How soon can I test based on my symptoms?

I literally just went off bc 3 weeks ago so I'm not even sure if I ovulated. My SO and I BD regularly. For a few weeks now I've been feeling nauseous. Last Wednesday I had weird cramps and everyone since I've had a fullness feeling in my abdomen. I've had back pain for 2 days now and extremely sore nipples for 3 days now.

Assuming I'm on a 28 week cycle (which I don't know since I have yet to have a period off bc), I still have 1.5 weeks until my period. I took a test Friday that was negative. I'm dying to take another but can't decide how long I should wait to take another. What do you think?
