Stomach shape

Ca

Does any one else have a weird stomach shape? I had a “normal” one😂 up until about a week ago. Now it’s like a flat ledge under my boobs and it looks uneven. I had ultrasound last week and was told he’s head down and as low as he can be without “coming out” 😑 so I’m not worried that’s he’s in a bad position.. just don’t remember this with my daughter. Could it be because he dropped last week? 37 weeks on Tuesday. Thanks in advance !
