Feeling sick

I'm on the pill but sometimes I do forget to take it on the night and end up taking it the next morning/afternoon. The pill is the only birth control we use. I've been feeling nauseous for over a week now. On and off all day feeling sick and being off my food.. But really want chips and gravy ha!! Anyway. My last period was a couple of weeks ago so I'm not due for another week or so. I am going to test but when is it best to do it? I can't tell if I'm excited or scared haha 😁😁👶🏻👶🏻
