14 days late!!!!!

Ok guy/ladies. I have been feeling off for almost a month. I have been nauseous every single day as soon as I wake up and just as I lay down for bed for a month. I have been peeing like crazy. I have acne so bad I’m embarrassed to leave my house(have maybe had 10 pimples my whole life!!)(I’m 28). I am 14 days late on my period and idk what to do!

I have taken probably 7 pregnancy tests. Had a blood test done at my doctors office and all have been negative!

What should I do!?!?
