Am I pregnant?

I had unprotected sex 2 weeks and 2 days ago so 16 days ago. He peed before we did it just in case so it would help reduce the possibility of sperm in his precum?? But he pulled out before he came and he came on my stomach. Last night my boobs were sore and I woke up today and they aren’t as sore but they feel as if they grew a tiny bit like I feel different? Could I be pregnant? Before anyone says don’t have unprotected sex if you don’t want to get pregnant, I get it, I was extremely horny and i would prefer if I wasn’t pregnant but if I am it’ll be a struggle but yay starting my family early??😂
