Sharp and her husband will be in the delivery room in August alongside Stoner and her husband as they welcome their son and nephew, respectively.

\"We feel so unbelievably honored to be his parents and raise him,\" said Sharp. \"A lot of love brought him here.\"

Sharp, an artist and architectural design representative, and Stoner, a registered dietitian, said they have learned firsthand through their journey the importance of women listening to their bodies.

They are now the co-hosts of a podcast, \"Talk to Me Sister,\" that's focused on women's health and advocacy through the lens of their own journey.

\"I'm lucky I had a twin sister who is educated in women's health and who has had babies in the past and miscarriages in the past, because had I not talked to my sister, I'm not sure I would have gone to the doctor,\" said Sharp of the doctor's visit that led to her cancer diagnosis. \"What I've learned along the way is even if there's a light intuition that this may not be normal for me, I listen to it. it's usually my body telling me that something is off.\"

Choriocarcinoma, which affects 2 to 7 of every 100,000 pregnancies in the United States, has a low cure rate if it is not caught early and spreads outside of the uterus, according to the American Cancer Society.

\"In the U.S., this is just a rare complication of pregnancy that many women don't know anything about unless they are faced with this diagnosis,\" said Dr. Alpa Nick, a Nashville-based gynecological oncologist who treated Sharp. \"The most important thing is continuing your annual care and your well-women care after pregnancy. Keep your postpartum follow-up [appointment] and stay in touch with your doctor.\"

Nick, like Sharp and Stoner, also stressed the importance of women using their voice when faced with a diagnosis like this that threatens both their lives and their fertility.

\"If fertility preservation is important, the first thing they have to do is say it out loud to their oncologist, and the earlier the better,\" said Nick. \"With Sarah, we were able to stay focused on what her goals were and think about her cancer treatment in terms of survival, but also in terms of what she would want down the road after she survived this.\"
