Hello So it has just occurred to me that my dad has a twin brother and his sister is also a twin (the other baby didn't survive). Now I'm slightly worried as I looked up Hyper Ovulation. My dad has 5 brothers and sisters all with more than one child. So I have about 15 cousins/sister and none of them have had twins yet, not all of them have had children though. It would just be my luck tbh. I'm so stupid for not realizing before and I'm sure it asks in your medical notes, to which I probably put no. Duh!
