Bikinis while pregnant

Sh
How do you feel seeing/being a pregnant woman wearing a bikini? My boyfriend and I are going on a trip in March and I will be 5 months then, I want to wear a bikini as I always have. He told me to wear whatever is comfortable for me. His mom overheard us and told me that she thinks its disgusting when a pregnant women is showing her stomach. She isn't going on this trip with us, so she won't see me. Her opinion got to me, is it really that gross? I have always found bumps to be beautiful and never thought twice.. now I'm scared of being judged?
