Testing after having sex.

Tina • God. Husband. Family. Due 12/2/15 with baby #1!
I was do you from my period on Sunday and it hasn't come yet, I took test on Sunday and Tuesday both with bfn. I just had sex with my husband before he left for work, and I wanted to take another text. But I didn't know if having sex right before (or within a couple hours) would change the result.. ??
