близнаци
Баба ми от страна на майка ми е имала еднояйчни близнаци. Дали не може да се изчисли вероятността това да ми се случи и на мен :)
Бременна съм в 18 г.с. Казват, че е едно, но като гледам снимката виждам две. Не че разбирам (не съм мед. лице), просто имам много силно желание за близнаци.
Ако някой разбира, моля за коментар.

Re: близнаци
По-добре да пита в клуб "Бъдещи майки". Колкото за шанса да имате близнаци, намерих това по нета. С две думи, еднояйчните близнаци са въпрос повече на късмет, но при многояйчните има някаква закономерност.
While identical twins generally happen by sheer chance, there are several factors that influence your chances of having fraternal twins:
• Heredity: If you're a twin or if twins run in your family, you're slightly more likely to have a set yourself. Women who are fraternal twins have a one in 60 chance of bearing twins.
• Race: Twins are more common than average in African Americans and less common in Hispanics and Asians.
• Age: The older you are, the higher your chances of having fraternal twins or higher-order multiples. A 2006 study found that women over 35 produce more follicle stimulating hormone (FSH) than younger women. Ironically, increasing levels of this hormone are a sign of failing ovaries and declining fertility. But FSH is also the hormone that causes an egg to ripen in preparation for ovulation each month, and women with extra FSH may release more than one egg in a single cycle. So while older women are statistically less likely to get pregnant, if they do get pregnant, they're more likely to have twins.
• Number of pregnancies: The more pregnancies you've had, the greater your chances of having twins.
• History of twins: Once you have a set of fraternal twins, you're twice as likely to have another set in future pregnancies.
• Body type: Twins are more common in large and tall women than in small women.
