30 weeks no symptoms until now

Mimi • Hi I'm mimi I'm 27 with 4 boys! Now I'm expecting my first Queen👶🏽🎀👑
So I just started getting really sick the last last I just ate right now as I'm typing this and vomited a little! I didn't have any symptoms of pregnancy or morning sickness my whole pregnancy anyone else had or having a lil girl and experienced/experiencing this? 
Or could it be the U.T.I pills I been taking for the last week I haven't took one yet today because it says take with food I just te and already feel sick so I don't want to take it but I know I have to in order for the infection to leave completely! What you all think?
