Justene Alpert — popular actress and author — says she and her husband made the difficult decision to terminate her pregnancy after doctors said their unborn baby had a rare genetic disorder which made carrying the child dangerous for both mother and baby.

Justene shared her story on Instagram Tuesday … revealing she and her husband, Mason Trueblood, were just starting to tell friends and family about the pregnancy in December when they received a call from their family doctor.

The actress, who has credits to her name like “Rescue: HI-Surf,” “How I Met Your Mother,” and “9-1-1,” doesn’t say what disease doctors found … but she says they told her they highly recommended she terminate the pregnancy quickly … worrying for her safety — and making it clear the child would not make it to term.

Justene went through with the procedure a few weeks later … and it left her and her husband with a feeling of shame and guilt.

She praises her husband and her friends for picking her up … while also writing she shared her story so other women who have gone through a similar situation might feel less alone.

Justene ends her post with a message for her son, Mads Mason Trueblood … writing, “I loved you then, I love you now and I will love you forever.”
