In this fatwa:
1- There is nothing wrong in having sex during pregnancy unless that will harm the wife or the baby.
2- The principle of honorable cohabitation implies that one should not force one’s wife to do anything painful or difficult.
In responding to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
It is also common knowledge that sex during pregnancy poses no health risk either for the fetus or the mother in normal cases.
Therefore, the general Islamic rule of permission prevails in this case unless a physician or midwife advises the husband and wife against it because of special circumstances.
It is, however, advisable for the couple who are engaging in sexual intercourse during pregnancy to exercise caution and avoid positions or methods of intercourse that may likely prove harmful.
Allah Almighty knows best.
