No, there certainly is not a 100% chance that you will get pregnant if you have sex when you ovulate. When you ovulate, you are more likely to get pregnant, but it is not a sure thing since pregnancy depends on many factors.
If you are pregnant, you probably won't notice symptoms until at least two weeks into the pregnancy.
