Do I look noticeable pregnant yet or not yet?

I'm going swimming with some of my family members - I don't get to see them that often as I live about 100 miles away from them. I'm not planning on telling them about the baby until about 20 weeks when I reveal the gender at the same time. This is my second pregnancy so question is do I look obviously pregnant or just bloated/weight from my previously pregnancy (my son is only 6 months and haven't managed to lose the weight yet)
