How early can women experience morning sickness?

I know this is a long shot, but I was at peak ovulation on Friday and of course we did the deed. That was only four days ago, but today I woke up experiencing cramps in my stomach, almost making me nauseous. I've gone through two pregnancies and never had morning sickness so I'm not sure if this is what it feels like. Any ideas? TIA!
