I have 11 month old fraternal twin girls.I had my suspicions at 6 weeks that I may be carrying twins as I was starting to show.I did'nt have any morning sickness just really tired.
Identical twins are a fluke of nature where the egg is split in two and it can happen to anybody.
Fraternal twins are genetic and comes about when a woman ovulates 2 eggs that are fertilised by 2 sperm.The mother or father can pass this gene onto a daughter as in my case my father passed on the gene to me.He has fraternal boy/girl twin cousins.My girls now have an even greater chance of conceiving twins as ther is the gene from me and also they are fraternal twins which makes them concieving twins 1 in 17.(thats pretty high)I believe I also have a 1 in 4 chance of conceiving twins next pregnancy.

How exciting if you are carrying twins it really is a blessing....
