Pregnant and feeling vulnerable in public

I typically don’t run errands often or go to crowed places besides grocery store and target 😂. Today I went to the mall and I felt unsafe due to my 6month pregnancy belly. Malls are typically are packed with fast moving ppl that dont pay attention to others. While inside Zara an employee was moving very fast on both sides of me putting away clothes . This made me feel uncomfortable like she was going to bump me; I wanted to warn her that I was pregnant and to not do fast movements around me.

Does anyone else feel vulnerable going out into large spaces where crowds will be . ?
