How long did it take?

How long did it take for yall to find out you were pregnant? Im 12 days late on my period with no lifestyle changes and my tests are all negative, i think, bc its only been 3 weeks since having sex during ovulation. My boobs have gotten bigger, my lower belly is sore, im getting nauseated over nothing. Like the scent of marinara sauce almost made me puke at work.
