The mother-of-one was taken to hospital in LA on Tuesday, 28 April after her vehicle was rear ended by another driver. Thankfully, her unborn child was okay.
Lisa shared a photo from her hospital bed, telling fans: "When some a-hole rear ends your car and you have to spend 24 hours in L&D getting monitored as standard protocol.
"Baby is fine but I'm losing my mind up in here!"
Lisa said she'd cried on the phone to daughter Pearl, three, because she hadn't been able to put her to bed.
"Feeling so much sympathy for the women who have to be in this unit on bed rest for weeks and months due to serious complications. My heart goes out to you."
After being monitored in hospital, the star was allowed to return home, where she took a bedtime picture with Jack and Pearl.
"Finally back at home with my crew! Thanks for all the well wishes. Baby & I are good :)."
Lisa and Jack announced the pregnancy in February.
