Need help! Something weird happened!

So my one clutch is due and she is laying now. I checked in with one of my other females who had her post ovy shed on march 22. When I looked I found these, is it normal for a snake to slug out this early? Usually it's still 30 days. She is 10 years old and 3000grams. So I am confused????

That really sucks!
I have heard of females throwing a slug a week or so before they lay, but can't say I've seen or heard of them doing this.
Hopefully someone with some more experience can chime in.

Yeah, I was shocked! At first I thought it was something else!
