I see so many twin moms to be on here posting “I’m having fraternal twins 6 weeks” or 8, 10, 12 weeks etc. If you’re having boy/girl twins then yes they are obviously fraternal but at that stage you don’t know the genders. Di/di twins still have a 33% possibility of being identical and there is no way to know until they’re born. Mamas: don’t count on them being fraternal if they’re di/di and the same genders!
