Yes, she uses "freeze pills"

Selina came out of the tub after washing herself in the hot tub. Fortunately, the air inside the tent was warmed by the electric heater in the tent.

Selina picked up the tablet which she had taken from Victor and pulled out one of the blue capsules. It was time for Selina to stop her possible pregnancy with these pills before it was too late. Selina sat on the bed, spread her legs, and slowly inserted the capsule into her vagina.

At first, Selina didn't feel anything special, but after a few seconds, she gradually felt the coolness inside her, and the cold inside her grew more and more.

"Oh, how cold it is, I hope it doesn't freeze my whole pussy" Selina said to herself.

Selina heard a faint sound from her cowl on the floor. Selina puts the cowl back on and said, "is that you Holly?"

After a few seconds, the voice came back and said, "Yeah, Selina! Where have you been all this time? I'm worried about you!"

"Oh, I'm sorry, darling, I took off my cowl I'm now in the James Brothers camp near Gotham. I can't come home today. Sorry that I spoke badly to you, I was nervous, thanks to Mr. Freeze, the problem I was worried about was solved. "

"Yeah, I saw everything with the camera. I'm not leaving you alone," Holly asked.

"Thank you, my love, know that i love you like my own daughter, and the reason I'm risking so much to make money is to finally be able to make a good life for both of us" Selina said.

"You're too young to be my mother, but thank you, I owe you everything, and you really cared for me like a mother," Holly said with a laugh.

"Thanks, take care of yourself and don't forget feeding my cats" Selina said.

Then Selina said goodbye and took off her cowl again and went tired under the blanket,she wad so tired that she fell asleep quickly.

*****************

Selina woke up to the loud rustling voice coming from outside her tent.

"Hi, It's Albert. I brought you breakfast, should I bring it to you? Or should I leave it here?"

Selina looked at the clock, it was 12 noon, and she slept enough.

Selina took off her blanket and sat down on the bed.
