Im new to this forum but had. A quick question. I'm pregnant for the 5 th time and have a wonder ful ds from my first pregnancy. However after going thru so much trouble and finally getting pregnant again I'm quite anxious. I also keep having the word twins running thru my mind. My ds ( who is 4) is telling me that there is both a boy and a girl in my tummy when he is asked if he wants a little brother or sister. Just wondering if any one can put my mind at ease and tell me what is going on.
