Confused

Hayden
I'm 9 days late and still no bfp. I have had some mild cramping, heartburn, moody as can be, the girls have been really sensitive, my back has been hurting, and my appetite is through the roof. The only time my period has ever been late was when I was pregnant. I just had Mirena out 7/28 but my dr said that shouldn't be a problem what so ever and conceiving would be a breeze. My fiancé feels like it's his fault but I don't think so because he is so young(19). I know I'm not out til AF shows but Jeeeze. I need a sign here.
