Sex is generally safe throughout a pregnancy without complications.
When you are pregnant, you may notice your desire for sex changes from trimester to trimester. The first trimester brings everything new including physical changes like breast tenderness, fatigue, nausea, vomiting and fears of miscarriage. You may notice a decrease in your sexual desire at this time. For a lot of women, these symptoms subside in the second semester offering a notable increase in sexual desire. Physiologically, blood supply to the pelvic area is enhanced, creating greater sensitivity and stronger orgasms. As the belly grows, sex in the third trimester can become a challenge. Some couples become nervous about harming the baby. Be sure to discuss your needs for intimacy with your partner. Experimenting with various positions can be helpful.

If you have a history of recurrent miscarriage or premature labor, your doctor may recommend you abstain. Additional reasons to abstain from sex may include:

• a history of miscarriage, premature labor or premature delivery
• cramps or bleeding
• placenta previa
• infection in either partner
• pain with intercourse
• leaking fluid or breaking of your bag of water

If you are unsure and have any questions or concerns about sex during pregnancy, be sure to speak with your doctor or midwife.
