Pregnant Gisele Bündchen Says There's 'No Perfect Roadmap to Follow' in Life After News of Baby No. 3

The supermodel is expecting her third baby, her first with boyfriend Joaquim Valente

Gisele Bündchen is taking some time to reflect.

On Thursday, Nov. 21, the pregnant supermodel, 44, opened up about the ability to choose her own life path on Instagram after news was revealed last month that she is expecting her third baby, her first with boyfriend Joaquim Valente. The soon-to-be mom of three shared a photo of herself peacefully enjoying a drink by the water and reading a book.

"There’s no guide to life, no perfect roadmap to follow," she wrote in her caption. "But remember everything you are, is a choice! To feel good, to be healthy, and to cultivate a positive mindset are daily choices that only you can commit to."

Last month, a source exclusively told PEOPLE that Bündchen is “excited” about her third pregnancy.

The source said that the supermodel feels good about the pregnancy. Bündchen has not shared the baby’s sex because she is not planning to find out herself until the baby is born, the source told PEOPLE, adding that Bündchen is several months along and plans to welcome her baby at home.

“Gisele’s very happy in Miami,” the source said. “She enjoys her life there. Everyone’s thriving.”
