Did any of your kids talk about their sibling in womb before you knew what they were and been right?…

Did any of your kids talk about their sibling in womb before you knew what they were and been right? I didn't know I was pregnant until last thursday, but my daughter has been talking about her sister AND brother in my belly for over two weeks now. I don't have my first ultrasound until the 25th and I know that's the only way I will for sure know if there's indeed two in my belly. What were your symptoms with twins!? I haven't been sick at all, and I was SO sick with all of my other pregnancies. My boobs have also doubled in size and they've never done that. And I know the muscles fall forward faster after the first (this is my 4th pregnancy, third term, my second ended n miscarriage at 9 weeks) but i legitimately went from not looking pregnant at all to looking like 3 months in a week. Lol
