Sarah Herron expecting first baby with Fiancé after IVF

Sarah Herron is going to be a mom.

The 35-year-old former contestant of The Bachelor and her fiancé Dylan Brown welcomed their kid, they revealed on Instagram on Wednesday.

"After a year-long IVF [in-vitro fertilization] journey, we are over the moon to confirm that our most recent embryo transfer was a success and I am pregnant with a baby boy!" Herron reveals to PEOPLE.

"We are early in the first trimester still, but since I have shared my fertility journey so openly with my community, it's important to me to that I continue in that faith."

"Dylan and I know the road ahead is long, but we are cautiously optimistic. We are so grateful for our fertility doctor, Dr. Aimee Eyvazzadeh who has helped make this a reality," she continues.

"We have completed 3 rounds of egg retrievals and one embryo transfer that ended in a chemical pregnancy in 2021."

To share the good news, the soon-to-be mother posted a number of adorable pictures of herself and Brown clutching an ultrasound image and a pair of baby booties on Instagram.

Herron adds that she and Brown "saw our baby's heartbeat flicker for the first time" this week and that she is seven weeks along in her pregnancy.

The Bachelor in Paradise alum has previously been transparent about her fertility and IVF struggle. She announced her engagement to Brown in May 2021.
