Measles at 18 weeks pregnant!

Hey ladies, ive just recently moved to the city and weve had 3 measles warning come home within threw weeks saying things like if youve been at this place on this date get checked etc-

Now my partner works at one of the places and was around his co-worker who has been checked and come back with DEFINITIVE measles results, I'm noy fully protected as i didnt get my second shot as a kid-

can i get a measles booster now even though I'm pregnant and will it hurt the baby?

Has anyone contracted measles and everything ended up okay? I'm stressing a bit..
