Lol I’m stressing!!

So I think I could be pregnant but I think it’s my body playing tricks on me. I had sex on the 19th and I know he nutted in me😭🤦🏽‍♀️but I never been pregnant or had a pregnancy scary before. So idk if it’s too early to take a test or if I should wait another week or two. HELP ME

PSA: that was my week of Ovulating and I’m 19.
