Need an advice

Ladies I need your help I feel sick and it's 3:50 am I've been feeling a here/there nausea. But I'm not hungry. So I warm up some plain chicken flavored rice with ketchup. Yeah I know. I also feel bloated below my belly button. I'm assuming a enlarged bladder at this point. Or an infection. But nothing adds up. My cycle lasted 2-3 days this time. See I've been trying to convince for 6 yrs if this is my first time l, I would not know how to tell the difference. O and I still feel that nausea after just one plate. Im hoping you know.
