The former TOWIE star posted a positive message on the photo networking site, saying she was "independent" and "strong".
"I can see my future and I can't wait to meet you," she said. "#everythinghappensforareason #focused #fit #clean #loyal #career #independent #changed #grown #strong."
Lauren's Instagram post comes as she revealed she is taking time out of her relationship with boyfriend Jake McLean.
Lauren, who has previously called Jake her "soulmate", has now revealed in her latest magazine column that the pair have unfollowed each other on Instagram and haven't talked to one another for a week.
Jake is no longer living with Lauren in her Essex home and Lauren has blamed "stress" and not any major rows for the breakdown of their relationship.
The couple rekindled their romance in June after previously splitting in 2013. Their break comes after Lauren's love gesture over the summer when she tattooed Jake's name on her wrist.
At the time, Lauren said the tattoo was done on "impulse" and Jake laughed and thought she was "mental" for getting it done.
Lauren and Jake hit headlines last year during their first split when it was reported a video clip had been taken from Jake's mobile phone which showed Lauren in an intimate position. Lauren said she believed Jake hadn't leaked it deliberately.
