22 days late

Okay so I am now 22 days late. I had taken a few tests and they all came back negative. So that night i decided to get myself a drink. I’ll admit i had added enough vodka to get me tipsy which doesn’t take much but not nearly enough that i would be hung over the next day. But even if i was that morning i wouldn’t have questioned it. But i had the WORST hangover i have ever had and i have had double, even triple what i had that night and have woken up fine. Same drink, empty stomach. That hangover lasted me over a day of barely being able to walk, vomiting, all that horribleness. I have heard of girls getting a negative pregnancy test and then after having an unusually bad hangover they found out they actually were pregnant. I have lightly bled before i was supposed to get my period and cramped a little. But the blood wasnt even enough to fill a light tampon. Im nauseas after everything i eat, my hormones are all over the place, and still no period. I have now taken 6 pregnancy tests to be absolutely certain and booked an app. with my doctor. Im not expecting pregnancy at this point but somethings up. I feel like im going crazy. Maybe some advice or words of encouragement could help
