During the 9th month of pregnancy, finding a comfortable and safe position for intercourse is essential. The best positions include side-lying, spooning, or woman-on-top, as they minimize pressure on the abdomen and provide better support. It's important to communicate with your partner about any discomfort or pain you may experience. As long as there are no complications or medical restrictions, having sex during this period is generally considered safe. However, it's crucial to consult with your healthcare provider to ensure it is appropriate for your specific situation.
