Wore a short and my family is looking at me weirdly

Yesterday I wore a short too. Nobody said anything, it was perfectly fine. Today, I wore another short. I got in the room, my father was like “are you crazy? You wore a short?” Then I went upstairs to my aunt’s office to say hello, and she was looking at my legs all weird, then I said hi to my older cousin, he stared too...

I’m so uncomfortable now, I want to leave. I’m on my period and it’s 30 degrees outside, i’d die from heat if I wore a jean. My short isn’t even that short, it is 5cm above my knee and covers my whole butt and even more than that, and it’s flowy, it doesn’t stick on my butt. My yesterday’s short was the exact same length and type. I feel so awkward...
