I have 6 year old twins (fraternal twins, which means they are not identical & this is the most common type as it is a hereditary trait). We did not have ANY family history of twins anywhere that we could find. My doctor suggested that because I was taking prenatal vitamins for several months before I got pregnant, and conceived very quickly after stopping birth control, that I actually produced miltiple eggs causing me to conceive fraternal twins. I found out I was expecting two at around 7 weeks. Hope this helps!! And if it is indeed twins, best of luck! They're such a blessing!! Built in best buddy ;)
I didn't think I had any history of twins. After I found out I was prego with twins (I'm 22 weeks) We did some digging. Found out my grandma' s sister was a twin. That's the only one we know of. But you could be prego with identical twins- you don't have to have any family history for that type of twins.
