Might be pregnant? When did y'all take a test?

Ruby

Hey girlies I'm 18 and had sex with my now ex boyfriend on February 10th. It's been two weeks but I don't want to take a test too early. I haven't had any symptoms that I know of? I felt very nauseous for about a week after we had sex but that's too early for symptoms I think. Should I take a test now or wait another week? My period is supposed to start on March 9th.
