That's what it was for me. They do make jeans with a sweatpants like waist for maternity, but... I avoided those. I think that most teens do. I just found myself in leggings and sweatpants. It was hard finding ones that were long enough for me. I really don't know why they called it that. Maybe the majority of women experience it in the morning.
I'm not sure how my dad would have taken this. I just know that I'm lucky to live with my moms and sister.
