I don’t know what to think😥 Help please

Sarah • 29 • Baby Girl #1 11-3-19💕 • Baby Girl #2 2-8-21💕

So my period is due in 4 days, i have mild cramping here and there, my boobs are super sore and feel really heavy, i threw up twice yesterday, still kinda nauseous, I’ve had a headache for almost a week now, and I’ve been really bloated. Took 2 pregnancy tests yesterday and they both came back negative. None of these are symptoms of my period coming. What could this mean?
