Yes, it is generally safe for a woman to have sex during the eighth month of pregnancy. However, there are some factors to consider and precautions to take. It is important to communicate with your healthcare provider and ensure that you have a low-risk pregnancy without any complications. Additionally, certain positions may be more comfortable than others, such as side-lying or using pillows for support.
