If your spouse is Canadian, then the baby is Canadian whether born in Canada or anywhere in the world. Please do inform CIC about your condition but i honestly dont see any reason according to their rules that they will expedite your case due to pregnancy. Since you are July applicant, you are in the same boat as mine, go to Mycic and check your processing stats. You are close in getting some decisions but since your medicals have expired and you are pregnant, i dont know how that plays out. Congrats on your pregnancy..
