Little help please

Asiyah

I ve been having these symptoms nausea, cramping on and off, terrible acne, dizziness and almost blacking out, also alot of fatigue and gas! I'm burping alot. I also feel like I have this lump in my stomach(thought it could be because I've lost my appetite) and I'm eating but still feeling nauseous and gassy... Can this be a sign of pregnancy? im 8dpo and tested neg.
