We had our ultrasound this morning and definitely have a little boy on the way. A healthy, little boy measuring 13 oz and 20w6d! The placenta is exactly where I guessed it to be - right in front - so it makes sense that I have only been feeling pressure there with movement down low, way on the left side and a small amount way on the right side.
My sister is now 6/6 for all the kids in our family. I'm going to start calling her the baby whisperer.
My DH is very happy as he and his brother are the only boys in his generation so only their children will carry on the family name. His brother's wife just had a hysterectomy, too, due to severe endometriosis and we aren't sure that they plan on adopting.
