I'm afraid to have twins. Seems like majority of people on here are?

Okay so it seems like it's so many people on this app that conceived twins and baby is due in August like mine. I just feel paranoid because the more I see twins, the more I think that I'm having them. My first ultrasound is so far away and I'm anxious to know. 😩😩. I've been dreaming about only one baby but still. Feeling worried.
