She has discussed previously the tragic 2009 loss of her son, Archie, 22 weeks into the pregnancy.
And, understandably, when Kym Marsh was presented with a hauntingly similar Corrie story-line for her character, Michelle Connor, she faced a dilemma.
Still, the 40-year-old actress ultimately decided to proceed with soap-opera plot, explaining: "I discussed it with my family and friends, all of whom were very supportive.
"In the end I felt it was an important story to tell in order to raise awareness of something which affects thousands of women every year."
However, the ordeal was not without its difficulties.
"I had to go to some very dark places in my mind whilst filming these heartbreaking scenes," Kym also admitted afterwards.
"But my family, friends and colleagues have been incredible.
"Losing a child is something that never leaves you so to revisit those feelings as Michelle has been challenging."
She added that Coronation Street ensured there was a counsellor on set at all times after filming the traumatic scenes. However, ultimately Ms Mash said the "best tonic" was "to go home to my kids and be reminded of how lucky I am to have them".
She has David, 20, and Emilie, 18, from a previous relationship. She also has five-year-old Polly, from her marriage to actor Jamie Lomas, which ended in 2013.
Archie died when Kym went into labour 21 weeks and five days into the pregnancy.
He died as soon as he was born.
Ms Marsh wrote in her 2012 autobiography: "He tried to take a breath and then he passed away. All I can remember then was silence. The midwife laid him on my chest, everyone started to cry."
Coronation Street will air the episide during the second week of January. Kym's on-screen husband Steve McDonald is played by Simon Gregson.
