For the past few days I have been feeling this weird nausea in my stomach and I feel something in the back of my throat but I haven’t been able to actually throw up. My period is late but it is very irregular always. Also I have been pregnant before and it doesn’t feel like the same nausea. It constantly there all day but there is a few brief moments where goes away. It sort of dims down when I’m eating when I don’t eat for a few hours I feel dizzy.
