I have bad nausea with my periods as well. Usually i get it a couple of days before the period and its horrible the day i start. I sometimes get some relief when it finally does start. I talked to my doctor about this and he said to take motrin a couple of days before my period. Something in the motrin alleviates the nausea. But remember, you have to eat in order to take motrin cause it will mess with your stomach if you dont. GOod luck, i hope you feel better
