Yes, it is generally safe for couples to have sex during the 8th week of pregnancy. However, it is important to consult with a healthcare provider as individual circumstances may vary. In most cases, as long as there are no complications or medical conditions that would advise against it, sexual activity can be enjoyed without harm to the baby. It is important to communicate openly with your partner about any concerns or discomfort you may experience and adjust positions or activities accordingly. If there are any concerns about bleeding, pain, or other unusual symptoms during or after intercourse, it is crucial to contact your healthcare provider immediately.
