Experiencing lower back pain and abdominal pain during the first trimester of pregnancy is relatively common. There are several potential causes for this discomfort, including hormonal changes, stretching of ligaments, and increased blood flow to the pelvic area. It is important to consult with a healthcare provider to rule out any underlying issues or complications. To alleviate the pain, you can try gentle exercises, applying heat or cold packs, practicing good posture, wearing supportive clothing or a maternity belt, and using over-the-counter pain relievers approved by your doctor. However, always consult with your healthcare provider before taking any medication during pregnancy. If the pain becomes severe or is accompanied by other symptoms such as bleeding or fever, seek immediate medical attention as it may indicate a more serious condition.
