I know that every pregnancy is different in every aspect, but when it comes down to symptoms...Things normally come along at the same rate. Heartburn doesn't "normally" begin until your uterus grown and begins to bush your stomach closer to your throat and esophogus.
Many times your body will give you false symptoms leading you to believe that you may be pregnant or maybe you've just eaten the wrong foods. Nausia is a definate symptoms. Fatigue is also a universal symptom that can happen as soon as the fetus attaches itself to your uterus.
Hope this helps and lots of lock to you and your fiance!!!
