It can be quite disheartening when the morning sickness you expected to fade by the second trimester decides to linger. Many people anticipate a "honeymoon phase" in weeks 14-27, so persistent nausea can feel confusing and frustrating. While often less intense than the early weeks, this lingering queasiness is still very real, and understanding its nuances can bring a sense of clarity.
Why it shows up this trimester
For most, the surge of hCG hormones that often drives first-trimester nausea begins to subside around week 12-14. However, other factors can keep nausea present. Elevated levels of progesterone and estrogen continue throughout pregnancy, which can slow down digestion, contributing to feelings of fullness, bloating, and sometimes reflux – all of which can mimic or worsen nausea. Dehydration, dietary triggers, or even stress can also play a significant role in this window. It's less common for nausea to be severe in the second trimester, but it’s certainly not unheard of.
