Pregnancy is a transformative time - emotionally, physically, and hormonally. One of the most common questions expectant parents ask is: “Can I still have sex while I’m pregnant?” The reassuring answer for most is yes, absolutely. Sex is a natural part of a healthy pregnancy, if you're feeling up to it.
From changes in libido to knowing when to take it easy, here’s your comprehensive guide to sex during pregnancy from our Midwife, Emily.
Is Sex Safe During Pregnancy?
Yes - if your pregnancy is considered low-risk, sex is completely safe at every stage. Your baby is snug and secure in the uterus, protected by the amniotic sac, strong uterine muscles, and a plug of mucus sealing your cervix. During intercourse or orgasm, your baby doesn’t feel pain or discomfort.
According to the NHS, having sex during pregnancy does not increase the risk of miscarriage. Many parents-to-be continue to have sex throughout their pregnancy, adjusting as needed to stay comfortable.
When to Avoid Sex During Pregnancy
Although sex is safe for most, your midwife or obstetrician may advise against intercourse in some situations. These may include:
- Placenta previa (when the placenta is low and covers the cervix)
- Unexplained vaginal bleeding
- Cervical incompetence (I prefer ‘A known short cervix’)
- Signs of preterm labor or contractions
- Leaking amniotic fluid
- History of miscarriage or premature birth
If your midwife has advised pelvic rest, this means avoiding penetrative sex, orgasms, and sometimes internal examinations, depending on the reason.
If you’re unsure, always ask your healthcare provider before resuming sex. What’s safe for one person may not be safe for another, especially if complications arise.
Pregnancy Hormones and Your Libido
Pregnancy hormones can have a big impact on your libido. And it’s completely normal for your sex drive to fluctuate.
You might find that:
- In the first trimester, nausea, fatigue, and breast tenderness leave you feeling anything but sexy.
- By the second trimester, many find their energy returns, and increased blood flow to the pelvic area can heighten sensitivity.
- In the third trimester, your growing bump may make intimacy trickier, and you may feel less inclined due to discomfort or anxiety.
Everyone is different. Some pregnant people feel more connected and in tune with their body, while others don’t enjoy sex at all during this time - and that’s okay too. What's most important is that you listen to your body and go at your own pace.
Safe Sex Positions During Pregnancy
As your bump grows, it’s worth experimenting with positions that reduce pressure on your abdomen. Some tried-and-tested options include:
- Side-lying (spooning) – reduces pressure and allows for closeness.
- Woman-on-top – you can control depth and movement.
- Rear entry (from the side or kneeling) – can work well later in pregnancy.
Communication is key. Talk with your partner about what feels good, and don’t be afraid to slow things down or stop if something feels uncomfortable.
Can Sex Trigger Labour?
It’s a common myth that sex can bring on labor. The truth? Unless your body is ready, sex won’t cause labor to start.
However, semen does contain prostaglandins - hormone-like substances that may help soften the cervix. And orgasms can cause mild uterine contractions. While neither are likely to induce labor before your baby is ready, in the final weeks of pregnancy (after 37 weeks), they might play a small role in getting things moving if your body is already preparing.
If you're close to your due date, having sex is considered safe unless your waters have broken. In that case, it’s best to avoid sex due to the increased risk of infection - check with your midwife if you’re unsure.
Emotional Connection and Intimacy
Pregnancy can bring couples closer but it can also introduce challenges. Changing body image, fluctuating hormones, and anxieties about the future may affect how you feel about sex.
Here are some ways to maintain closeness:
- Enjoy cuddling, kissing, and massage.
- Explore mutual touch or sensual time together.
- Have open conversations about needs and boundaries.
- Try non-sexual activities to strengthen emotional bonds.
Not in the mood for sex? That’s perfectly fine. Pregnancy is not the time to push through discomfort. Give yourself permission to rest and reconnect in other ways.
Protecting Against STIs
If there’s any risk that you or your partner may have a sexually transmitted infection (STI), it’s vital to use condoms during pregnancy. Some STIs can affect your baby or complicate pregnancy. The NHS STI testing service is free and confidential.
Speak to your GP or midwife if you’re concerned or want to get tested.
Midwife’s Top Tips
- Listen to your body. Your comfort is the priority—stop if anything feels painful or wrong.
- Stay communicative. Let your partner know how you’re feeling emotionally and physically.
- Use pillows for support, especially in the second and third trimesters.
- Don’t panic about the baby. They are well-protected and unaware of sexual activity.
- Always check with your midwife if you’ve had any bleeding, unusual discharge, or pregnancy complications.
Every pregnancy, and every relationship, is unique. Some couples have more sex during pregnancy, others less. There is no right or wrong, only what feels right for you.
Your changing body is doing something incredible, and taking time to understand, communicate, and care for yourself during this time is just as important as preparing for birth. If you’re ever unsure or uncomfortable, your midwife is always there to guide and reassure you.
