You just know if you are having a boy or girl?? I didnt with Luke my first I had no idea what to expect & was happy with either. This time feel like I know exactly what I am having. Again I do not care either way. I actually think I would prefer a boy. Everything I own & know is boy. But I cant shake the feeling I am having a girl. I told my husband I feel like its a girl cause I am not prepared for one (lol). But everything about this pregnancy is different the way I carry the way I feel I have had more trouble in 12wks of this pregnancy then all 9m of my last one. Only like 3 more weeks till I know for sure. The week before I find out my Husband and I are going to try all those old wise tales that are suppose to tell you the sex of your baby.
