Gestational timeline: 2nd Trimester & 3rd Trimester
Linea nigra is a dark line that appears vertically on the abdomen during pregnancy, typically in the second trimester. This pigmentation change is caused by hormonal fluctuations and increased melanin production. While linea nigra is harmless and usually fades after childbirth, wearing sunscreen and avoiding prolonged sun exposure can help prevent further darkening. It typically occurs during Weeks 23, 40 (2nd Trimester & 3rd Trimester) of pregnancy.

Here are other common symptoms that typically occur during weeks 23, 40:
During pregnancy, hormonal changes can increase blood flow to the gums, making them more susceptible to bleeding and inflammation, a condition known as pregnancy gingivitis. To maintain oral health, brush and floss regularly, and schedule regular dental check-ups. If you experience persistent or excessive bleeding gums, consult your dentist or healthcare provider for evaluation and advice.
Blurred vision or seeing spots, especially accompanied by headaches, could be signs of high blood pressure or preeclampsia, a serious pregnancy complication. If you experience these symptoms, particularly in the second or third trimester, consult your healthcare provider immediately.
Hormonal fluctuations during pregnancy can lead to mood swings, characterized by sudden changes in emotions, ranging from happiness to sadness or irritability. It's essential to communicate openly with your partner and healthcare provider about your feelings and concerns. Engaging in relaxation techniques, maintaining a healthy lifestyle, and seeking support from loved ones can help manage mood swings during pregnancy.
