Emily Maynard's family of four is about to become bigger.
The 30-year-old Bachelorette
star is pregnant with her third child, she revealed on her blog
on Tuesday. Maynard admits she herself was surprised with the baby news, given that she gave birth to her son, Jennings Johnson, just last July
. The I Said Yes
author says the newest addition to her family is due at the end of this summer.
"Well... I'm pregnant. Again," Maynard jokes. "And before you even say anything, yes, I realize I just had Jennings like, 2 seconds ago. I guess I should've read that part in the baby handbook that says you're super fertile after giving birth, huh?"
"When this baby gets here, Jennings will be about 15 months old and even though I'm sure he'll have no clue what’s going on, I feel a little guilty just because he didn't get to be the baby for very long!" she adds.
Still, Maynard is obviously overjoyed that she and her husband, Tyler Johnson, are adding to their brood.
"With all that said, I truly couldn't be more excited, and I said about two weeks after Jennings was born that I couldn’t wait to have another -- I just had no clue it would happen so quickly!" she writes. "Some of my closest friends have had a really hard time getting pregnant and my heart breaks for them, so I’m just so grateful for this blessing God has given our family."
"Tyler comes from a family of four boys and they couldn't be closer, so I'm really looking forward to Jennings having a built-in best friend, whether it's a boy or a girl," she continues. "[My daughter] Ricki is really hoping it's a girl so she can teach her how to be a tomboy and play soccer!"
The reality star married Johnson in June 2014
, after meeting in church. The newest addition to their family will join her 10-year-old daughter, Ricki (whose late father is NASCAR racer Ricky Hendrick) and 7-month-old Jennings, her first child with Johnson.
Last month, Maynard's fellow Bachelorette
star, Ali Fedotowsky, also announced she's pregnant
