More than likely, you'll be fine. Was it homemade or from a restaurant/jar? Aioli is basically just garlic mayo. If it's commericially prepared, it's as safe as any commercial mayo (which is to say, as safe as any other food). If it's homemade, then there is a slight risk, but if it was freshly made, then it's very unlikely you'll get sick. I've eaten uncooked eggs plenty of times since I've been pregnant and as you can see, we are perfectly fine.
