Mother Alina Dulgheriu has applied for permission to appeal an Ealing Council PSPO (Public Space Protection Order) that stops people from offering support to women with unwanted pregnancies.
Her application follows a Court of Appeal decision which said the ban was legal.
The dispute came about after Ealing Council introduced a censorship zone outside the Marie Stopes clinic which prevents any acts which shows disapproval around the issue of abortion. That includes audible prayer.
Ms Dulgherui is taking action after she herself was given support when considering a termination.
Hundreds of donors have supported her, contributing to a £50,000 legal fund.
She said: "My little girl is here today because of the real practical and emotional support that I was given by a group outside a Marie Stopes centre, and I am going to appeal this decision to ensure that women do not have this vital support option removed.
"I will continue to stand up for the women whose voices have been sidelined throughout this process and for women who need life-saving support today but cannot get it.
"Ealing Council could have taken action in a way that would have protected women and safeguarded the essential help offered at the gate. Instead, they criminalised charity and attempted to remove dedicated and caring individuals from public space without justification."
The judge at the Court of Appeal defended the right of the council to impose the PSP stating here was "substantial evidence" from clinic users that their privacy was being "very seriously invaded at a time and place when they were most vulnerable and sensitive to uninvited attention".
