## TLDR

- In an uncomplicated pregnancy, sex is safe right up to labor and doesn't cause miscarriage.
- Your provider may advise against it with placenta previa, preterm labor risk or waters broken. Light spotting after sex is common.
- Never let a partner blow air into the vagina. Bleeding heavier than spotting or cramping that keeps coming means call.

## Is it safe?

- In an uncomplicated pregnancy, sex is safe right up to labor, including oral sex, penetration and
  orgasm, with any partner or on your own.
- The baby is protected by the amniotic fluid, the strong muscles of the uterus, and a mucus plug in
  the cervix. Penetration can't reach or hurt the baby.
- Sex does not cause miscarriage.

## When your provider may advise against it

- Placenta previa (placenta covering the cervix) in the second half of pregnancy.
- Preterm labor, a short or open cervix, or a history of preterm birth, depending on your situation.
- Your water has broken.
- Unexplained bleeding until it's checked.
- Ask exactly what "no sex" means for you: penetration only, orgasm too, or all sexual activity.
  Advice differs, and other kinds of closeness are usually still fine.

## What's normal

- Light spotting after sex: the cervix has more blood flow and can bleed a little when touched.
- Mild cramps or tightening after orgasm that fade within an hour.
- Desire that rises, falls, or swings: often low in the first trimester from nausea and tiredness,
  higher in the second with more blood flow, and lower again late on as comfort drops. All are normal.
- More discharge and vaginal sensitivity. A water-based lubricant helps with dryness.

## Making it comfortable

- As the bump grows, try side-lying (spooning), being on top, sitting on the edge of a bed, or
  hands-and-knees. Avoid long stretches flat on your back after mid-pregnancy.
- Go slower and use pillows for support.
- Breast tenderness is common; say what feels good and what doesn't.

## Things to avoid

- Never let a partner blow air into the vagina; in rare cases it can cause a dangerous air bubble in
  the bloodstream.
- If you have a new partner, or either of you has other partners, use condoms. Some STIs can harm a
  pregnancy or the baby at birth, and testing is part of prenatal care.
- If a partner has traveled to a Zika area, follow CDC advice about condoms for the rest of the
  pregnancy.
- Clean toys well; don't move from anal to vaginal contact without washing or a fresh condom.

## Intimacy beyond sex

- Many couples feel close in new ways: massage, baths, cuddling, talking about the baby.
- Partners sometimes worry about hurting the baby or feel unsure about the changing body; talking
  openly helps.
- Body image changes can affect desire. Kindness from yourself and your partner goes a long way.
- For trans and nonbinary parents, pregnancy can bring up dysphoria; a supportive provider and
  partner can help you find what feels right.
- Sex near the due date is sometimes suggested to start labor; there's little evidence it works, but
  it's fine if you want to.

## When to check in

- Mention pain with sex or a big change in desire at your next visit.
- Contact your provider the same day for bleeding heavier than light spotting, fluid leaking, or
  cramping that keeps coming after sex.
- If you have heavy bleeding or severe belly pain, call 911.
