Pregnancy is the period during which a fetus develops inside a woman’s uterus, typically lasting about 40 weeks from the first day of the last menstrual period. In the United States, around four million births occur each year. Pregnancy is divided into three trimesters, each marked by distinct stages of fetal development and maternal changes.

Symptoms vary widely but often include missed periods, nausea, vomiting (commonly in the first trimester), fatigue, breast tenderness, and mood changes. Later symptoms can include back pain, swelling, and frequent urination as the pregnancy progresses.

While pregnancy is a natural biological process, it can come with complications such as gestational diabetes, preeclampsia, anemia, or infections. Regular prenatal care is essential to monitor the health of both mother and baby, manage symptoms, and catch any issues early.

Treatment during pregnancy focuses on supporting maternal and fetal health. This may involve lifestyle changes, prenatal vitamins (especially folic acid and iron), and medications that are safe for use during pregnancy. Common concerns such as nausea, heartburn, and constipation may be managed with antacids, antiemetics, or stool softeners, depending on the case.

Only drug classes and medications considered safe for pregnancy should be used. It’s crucial that any treatment plan during pregnancy is guided by a healthcare provider to protect both maternal and fetal well-being.
