Serena Williams recently took home the Australian Open title in her first trimester, joining a long line of women who haven't let pregnancy stop them from kicking some serious butt.

1. Won the Australian Open.

Thirty-five-year-old Serena Williams has 23 major titles to her name. Now, she can add another title to her collection: mother. Williams announced she was 20 weeks along back in April, which meant she was in her first trimester when she won the Australian Open back in January.

2. Raced to the delivery room.

In 2011, Amber Miller made headlines around the world when she gave birth to a daughter just a few hours after crossing the finish line of the Chicago Marathon. The 27-year-old completed the race in 6.5 hours, and though she walked for parts of the race she still beat her husband’s time!

3. Swam the English Channel.

Regan Schreiber tackled the English Channel while pregnant back in 2001, completing the 30-mile crossing in nine hours and 30 minutes. She was 11 weeks pregnant. (The slowest swimmer on record made the crossing in 28 hours and 44 minutes.)

4. Slid her way to Olympic silver.

Canadian Kristie Moore was five-and-a-half months pregnant when she hit the ice during the 2010 Winter Olympics to curl against Sweden. Her team won that match, though Sweden went on to take the series. Moore came away with a silver medal, and not long after, a baby.

5. Fought in Afghanistan.

Kayla Donnelly, a soldier in the British army, served in Afghanistan while pregnant in 2012. Though women in the military are typically not allowed to deploy during pregnancy, Donnelly was unaware that she was pregnant, and gave birth unexpectedly.

6. Served in the House of Congress.

In 2010, after giving birth to her second child, politician Cathy McMorris Rodgers became the first congresswoman to give birth twice while in office. Four years later, at the age of 44, she was still in the House when she broke her own record and gave birth a third time.

7. Baby? Checkmate.

Chinese chess Grandmaster Xu Yuhua was three months pregnant when she won the 2006 Women’s World Chess Championship. Then 29, she stated that her baby was the one to help her outwit her opponents.

8. Walked her sister down the aisle.

Most bridesmaids have their hands full with wedding-day responsibilities, but Lucy Morris proved her dedication when she walked her sister down the aisle while in labor. Admitting after-the-fact that she was in “agony,” the then 29-year-old managed to hold on until after the ceremony before heading to the hospital to deliver. Her daughter Izzy was born 13 hours later.

9. Photographed her own birth.

Wedding portrait photographer Lisa Robinson was joking when she first suggested photographing her own birth. But the thought took root, and in December 2015, Robinson captured one-of-a-kind images of her own labor and delivery, including images of her husband’s first glimpse of their daughter and the doctor holding her daughter mere moments after delivery.

10. Scaled some serious rocks.

Back in 2012, hard-core climber Aimee Roseborrough appeared on Good Morning America after climbing actual mountains well into her eighth month of pregnancy. The veteran climber claimed that climbing was an escape and she’d sometimes “forget” just how huge she was.
