I think I’m pregnant

Me and my partner had sex without protection the same day my period went and I should have another period in 7 days but for the past 4 days I have been nauseous, watery mouth, lower abdomen cramps and certain smells just set me off, I am so anxious that I took 2 different pregnancy test but both were negative. I am never been so impatient for my day to come, I wanna fast forward those 7 days.... my problem is we had sex at a safe period🤦🏾‍♀️🤷🏾‍♀️😑
