Twilight: Lunar Eclipse

Party

Bella's PoV

We finally arrived at the main house.
I was greeted by Renesmee or Nessie (I still hated having to force myself to call her that) jumping on me and hugged me tight. I swear if I was still a human I could've fell right back and hit my head hard on the firm, solid cement ground, but, I wasn't, so I'm lucky I could live.

"Mummy!!" Ness screeched.
"Yes darling?" I asked.
"Hurry up! We're going to be doing something!!!!" She answered back. I opened my mouth to speak but she cut me off immedietly. "Ops!" She said while raising her hand in front of my face. "No asking cause I'm not telling!" She continued. "Fine." I said then followed by pouting. I then looked at Edward knowing that he just read her mind. I nudged him on his side. "What is it that were doing?" I asked. He turned his face to me (cause he was staring at the house) then answered: "She doesn't know either. Jacob is planning it at the end of the party." "Anything else?" I asked crossing my arms raising an eyebrow. "Uh. Ya. She's excited for the Denali's to arrive but they'll be here probably, right as we enter the house."

When the Denali's arrived, Tanya practically jumped on Edward hugging him tightly, while Edward was trying to get her off his body. Once she got off, we started the party. We had quite some fun as we played truth or dare and the drinking game which was hilarious because I found out Emmett would steal and apply Rosalie's lipstick when she wasn't around and pretend to be a stripper.

It finally ended until I remember that Jacob has planned us something or at least planned something for Renesmee and himself.

"Um, alright everyone, before Jacob announces his announcement, I'd like to say something that might make you happy by some reason." Carlisle said, stepping forward to the middle.

"Today is Valentine's day as you all know, and today is also the day that has only happened once to each female in a century each so it rarely happens. Some people like Jacob, Bella and Ness might not know because they are still new here."
"Today or tonight is the time where all female vampires will start having the same actions of a human female does. Since later on, all the couples here will be having some of their 'alone time' in a particular room in this house, men, you might be noticing your mates start to blush and that's normal for this time. At 12 it will immediately wear off. Just to let you know." Carlisle said and finished.

But there was one question that came to mind.
If all female vampires that has a mate might be having sex with them tonight with them acting like human and blood fluttering in their cheeks,
Doesn't that give them a chance to get pregnant?

"Anyways, Jacob will now be presenting his announcement." Carlisle said.
With that, Jacob stepped forward and I felt Edward tense beside me. I wonder what was going on?
