Should I go in??? 26 weeks pregnant

So I haven’t been feeling good and all of a sudden I have been starting to feel really light headed and like Just zoned out were I feel like I’m coming in and out. I’ve been super nausea my body feels horrible like I can’t even explain this. I am at risk for premature labor so that always stresses me out!! And I’m going #2 like every hour but it’s just normal? So idk what to do
