I didn't have any symptoms my whole pregnancy with my son. Well, I had the fatigue, cravings, and weight gain, but other than that, nothing. I had no heartburn, constipation, nausea, etc. I didn't even feel contractions until like an hour or so after my water broke and by then they were wheeling me in for a csection because my boy was breech. Every pregnancy is different. Maybe you are going to have an easy one this time.
