Abdominal pressure.

So I am having like abdominal pressure in my lower stomach, and it feels weird. I have been a little gassy the past couple of days, I did have some cramping about two days ago in my lower stomach as well, and after Saturday I have been super nauseous to where I smell some food I just want to puke, and thinking about certain foods makes me want to as well. I did drink Friday night so I thought it was because of that but it’s still going on. I took a test last Monday and I didn’t think it was positive. Should I test again or is it nothing to worry about.? I am also posting that test as well.
