10 dpo & feeling nauseous !

Hey guys, I woke up with pressure in my lower stomach on like the left side . So I went to grab something to eat (one of my favorite foods) and was even able to eat it. It actually made me very nauseous. I feel the urge to throw up. I don’t know what to think what do you guys think ? Please comment! (Period starts in 3 days) App is almost always accurate for me.
