My 3 year old says I have 2 in my belly!!

Does anyone else have this going on?? My 3 year old is constantly telling me or my fiancé that I have 2 babies in my belly. She will then say "that's my brother and sister in there" I have thought I was having twins here and there, I am way bigger with this pregnancy than with my first my Dr. even said I was feeling big. My fiancé has had multiple dreams I'm having twins and my mom miscarried twins when I was 5. I have my ultrasound tomorrow. 👶🏼😉❤️💟💙 I can't wait either way.
