Accidental peeing

I had sex this weekend and ever since I pee a little bit when I cough or laugh hard or anything like that... Similar to how pregnant or women who have had children describe it. I expected it to go away but it's been three days and I don't know what's going on. Is this normal and should I be worried? Am I correlating it to sex because that's when I noticed it even though they aren't related? Help me!
