Can you get signs of pregnancy only a couple days after sex?

Three-two days ago, I had sex for the first time and have been really anxious about it ever since because I’ve had abdominal pains, nausea, and pains urinating.

If anybody knows anything... show more Three-two days ago, I had sex for the first time and have been really anxious about it ever since because I’ve had abdominal pains, nausea, and pains urinating.
