Jessa, 22, announced her pregnancy on Twitter in April, writing, "Ben and I are so excited to announce that we're expecting a baby!!!!!"

She added that her due date is November 1, the couple's wedding anniversary.

"Baby Seewald" isn't the only new addition to the Duggar family this year. Just last month, her sister Jill and husband Derick Dillard welcomed a son, Israel David.

And Jill and Jessa's older brother, Josh, is expecting a baby girl with his wife, Anna, this summer.

On Tuesday, Jessa took to Instagram to send her husband Ben a heartfelt birthday greeting.

"Happy birthday to my best friend and favorite person in the whole wide world!!! @ben_seewald," she wrote alongside an image of the couple. "Life with you is always so fun and exciting!"
