Knowing that u were pregnant

Sequoia
Did anyone just know that they were pregnant before they took a test? Or did a family member tell you that you were pregnant beforehand? My mom and my SO and his grandma knew even before I did. My mom said that she could tell because I told her that I had a mcflurry everyday for a week straight. My SO said he knew because I peed a lot and my boobs getting bigger of course. His grandma said it was written all over my face.
