CHARLOTTE -- Protesters outside Preferred Women's Health Center is not unusual.

Misty Terrell volunteers to help patients find the clinic, despite the demonstrations. Which she believes can often cross the line.

“How would you feel if you went to a doctor's appointment and you had to go through a gauntlet of shame just to get an exam?,” Terrell said. "Someone threatened to hit me at one point. So it's gotten to that level."

Love Life Charlotte, a "Pro-life" organization, has been one of the consistent demonstrators at the clinic .

"I don't believe that prayer is ever a threatening situation,” Love Life Charlotte Spokesperson Jim Quick said. “We have a very strong code of conduct."

In its code of conduct, Love Life Charlotte tells members to not engage anyone at the clinic.

But Saturday it's inviting 7,000 people, more than 100 churches, and multiple pro-life groups for it's prayer walk.

“We've never had any issue of violence or unsafety,” Quick said. “We're here to celebrate life."

"I know that they frame this as a prayer march. But, unfortunately, their prayer is harassing and impacting other people,” Preferred Women’s Health Center administrator Calla Hales said.

Hales says the health center is doubling security Saturday. Its asked CDOT to post ‘No Parking’ signs along the road to keep the event from cutting off access to the clinic. And Chief of Police Kerr Putney said CMPD is providing increased protection.

“We've been in conversations with organizers on both sides to make sure everybody knows what the expectations are,” Putney said. “And we think it will be a peaceful protest."

Because there will be no parking on Latrobe Road, thousands of protesters will shuttle in for 90 minutes before the prayer walk at 9 AM.

“Over 800 women have chosen life because someone was standing here on the sidewalk,” Quick said. “So that's what we'll continue to do."

“Their presence has filled me with a brand new sense of purpose and I don't plan on stopping any time soon,” Hales said.

Saturday's prayer walk is the end of a 40-week program of demonstrations from Love Life Charlotte. The group says it will continue demonstrating and working to prevent abortions.
