Experiencing nausea and vomiting, often referred to as 'morning sickness,' is a hallmark for many in the first trimester. However, if these symptoms make a reappearance, or show up for the first time, in your third trimester (weeks 28-40), it's a signal to pause and connect with your care team.
Why it shows up this trimester
Unlike early pregnancy where hormonal surges are often the primary driver of nausea, new or worsening nausea and vomiting in late pregnancy is less commonly attributed to typical 'morning sickness.' Instead, it can sometimes be a symptom of other conditions that need attention. Your body is working incredibly hard in these final weeks, and while some general discomfort can arise, persistent or severe nausea and vomiting is not usually a 'normal' part of late pregnancy.
What it tends to feel like now
If nausea returns in the third trimester, it might feel different from your earlier experiences. It could be more intense, or it might be accompanied by other symptoms that weren't present before. You might notice it alongside a headache, changes in your vision, sudden swelling, or pain in your upper abdomen. These accompanying sensations are important clues for your care provider to understand what might be happening.
