Hi, Amber9999, and welcome!
It's definitely not because you're new -- it's more likely that people are out and about for the weekend and just haven't seen your questions yet :)
I see that you've gotten some responses to your posts, but you might want to check in again later tonight or tomorrow to see if you get more answers.
As for your earlier question about experts answering questions, I see that you did get an answer in that forum. You can see which of your posts has received answers by checking the posts widget on your profile page here:
