First

to the board!!! Please tell us about you and your dp... take a minute and answer the questions on the "getting to know you" thread! But, what ever you do stay a while!!!
I'm pretty sure twins are always determined by the egg or eggs not the sperm. There is always just one

that penetrates the egg/s.
2 or more eggs released + 1 sperm insemination = Fraternal Twins
1 egg + 1 sperm then it splits = Identical Twins
HTH

and



to you and your DP!!!
