11 weeks too early for maternity clothes?

I’m 11 weeks and my stomach is getting bigger every week and I feel like in the last week it’s gotten hard and i can’t suck it in anymore. Is it a bump or is it still bloat? I also can’t fit in my jeans and pants anymore so I bought a few pairs of maternity pants but I feel weird wearing them because I don’t have a huge bump is it too soon for them?
