I was wondering if anyone had ever had twins and been told there was only one. you see, I was 8 weeks when I had my first ultrasound where they saw a baby. I also have two other children. I'm really starting to wonder if they missed one, or if that's possible- i specifically asked the tech if there was only one and she said yes. I am about 16 weeks now, and I am already starting to get stretch marks on my belly- i am definitely larger this time around then with the other 2 kids. My mother was a twin, but her twin died in utero, my maternal grandmother was a twin, and so was my maternal great grandmother. I am the youngest in a long line of relatives and no one else in the extended family has had twins. but I swear my belly is getting too large for me to accept that all the extra belly is from eating. What do you think?
