I just had my first ultrasound on Wednesday and found out that we are having twins. I was completely shocked when the nurse told me. I still can't believe that we are having twins. I am only 8 weeks along so I don't know what sex the babies are yet. I do know that they are probably identical because they are in the same sac with a membrane separating them. I would like to hear from anyone else who is having or has had twins. I want to know what you are feeling? I'm not really having to much morning sickness. I have actually thrown up only once since I have been pregnant. Is this normal, especially with twins? I have been very tired, and hungry all the time. Please let me know if this is normal.
