( CNN ) -- Lindsay Lohan 's TV reality series ended Sunday with the actress laying some very personal cards on the table . In a scene from the season finale of OWN 's docuseries `` Lindsay , '' the 27-year-old explained that the reason she 'd missed some filming days for the project was because she 'd had a miscarriage . `` No one knows this : I had a miscarriage for those two weeks I took off , '' she said . `` It 's a very long story . '' During the docuseries , one of the plot points that emerged was Lohan 's inconsistency with showing up for work . But as she explained on Sunday 's finale episode , it was because she was unable to . `` That 's why , on the show when it says , 'She does n't want to come down , ' I could n't move ; I was sick , '' Lohan said . `` Mentally , that messes with you . '' OWN 's `` Lindsay '' covered a lot of ground with Lohan , following the actress after she left rehab in July 2013 and moved to New York while trying to repair her career . By the time the last episode aired , Lohan -- along with the rest of the world -- had seen the difficult footage of her post-rehab life . `` I cried so many times watching it , '' she said . `` Watching this series , I just know how I felt at that moment , and I can relate to that girl . Like , 'Oh my God , this is really sad . Who 's helping her ? ' ... There was a lot going on in my life then . '' Filming the eight-part series did impart some lessons , and one in particular was how her struggle with addiction could leave her without a career . `` Even if it 's not my intention to lose everything I 'm now working for , that 's what this addiction will do to me . It 's a really f***ked-up disease , and it 's really scary , '' she reflected . `` ( Now ) I 'm in a good place , and I do n't want to mess with that . It feels good , and I 'm happy . The biggest thing I 've learned from this experience and doing this show is that my work ethic is different . I have that fire back in me . ''
