Morphology
The meaning is directly and transparently derived from combining 'first' (preceding in time) with 'trimester' (a three-month stage), so it clearly denotes the initial three-month period. This ordinal + period composition is a straightforward, cross-linguistically common pattern, making the phrase immediately comprehensible to a learner who knows both constituents.
Etymology
First trimester comes from the word trimester, which meant a 'three-month period'. So first trimester means the first three months of pregnancy, the early time when the baby begins to grow.
