Went to my first ultra sound appointment. They said I'm 7w2d which brought me back one day (I don't mind! Much better than finding out I'm only 6 weeks or something!) Transvaginal. 143 heart beat. Have to go back in 3 weeks for physical and blood work, for genetic testing if requested. Just so happy/thankful to see and hear the heart beat today, I was so worried that maybe there was nothing in there since I don't feel nauseous.
