Night nausea

Dee • Pregnant with baby boy #2!!!
I wake up feeling great albeit a little tired. I take a nap with my son around 1 we wake up close to 3 and its just down hill from there. Super nauseous and fatigue until about 11. If I don't nap with him its so much worse. Read somewhere in an old wives tale that evening nausea means it could be a girl this time, anyone else?
