When rudeness triggers anxiety

I'm 9w4d today, and yesterday while visiting with family, it came out that I'm pregnant. I wasnt planning on telling this early, but since my husband and I are newlyweds, it's been coming up a lot. 

What gets me though, is my aunt. When she heard, she asked "already?" To which I happily told her yes, but only 9 weeks. Her reply was, "well, I'm not going to congratulate you until you make it to 13 weeks". 

Why would she say that?! Now all I've been able to think about is what if I dont make it that far. I've been trying so hard to stay positive, since this is my first, and I dont have any history that makes me susceptible, but it's a constant nagging worry in the back of my mind that I can't shake. Every morning when I wake up and my breasts dont hurt, or if I'm not nauseous it makes me think that there's something wrong. I dont go back to the dr for 2 weeks, not another US for 3 at least...Its driving me crazy... please tell me I'm not alone... how do y'all y'all deal with this?
