Yes, first trimester is pretty early to be buying stuff for baby.
But for a more comfortable pregnancy, you can get things like:
1. Nursing bra

2. Pregnancy pillow
3. Stretch mark cream (need to start applying already!!!)

This brand is very spreadable and not sticky or oily at all.
Hope this helps and congratulations!!
