I have just had my second little man. My first turns 2 next week so was a little older than yours when I was in my first trimester.

I was concerned as well but my GP said bubs is very well protected so there is really nothing you need to do differently. Just listen to your body. When you get uncomfortable, then you know to change what you are doing.

I found that as I got bigger, it got very uncomfortable holding DS1 on my hip as it through out my balance and made my back sore. I just moved him to the front and had him sit on my arm instead. Just minor adjustments.
