where is my nausea???

Erica
A week ago I was feeling nauseous several times a day, especially middle of the night. But for a few days now I have no nausea at all... I know there are plenty of you who would love to trade places but I can't help but worry... I still have sensitive boobs and pee a lot and am constipated, but that could all be pms! No cramps or bleeding and keep getting bfps but am still freaking out. Does anyone else have no nausea?
