Sick and pregnant

Jenny β€’ We're expecting our first baby due Nov. 14th!πŸ’–πŸŽ€
Does anyone get sick during pregnant? I was so sick for the last few days and I think it was flu :( 
By the way is it normal for boob stop being sore and decrease morning sickness? I used to have morning sickness for a week until it stopped yesterday morning. Is it normal?
