Do you think she's building?

I also tried palpating her, but I really have no idea what I'm doing

Here's how I palpate, maybe it will be easier for you.

I find a table leg, I use my heavy coffee table, and let the snake on the floor to relax for a few moments and then guide the snake so it's neck grabs the coffee table leg and it pulls itself away from you.
When it does grab it with your middle two fingers of each hand pushing up on the belly let it slide through your fingers while you gently squeeze the belly pushing upwards with those middle fingers.
I use my thumbs to hold the top of the snake down so it glides through my hands.
I found this pretty easy to feel the belly and you may not feel small follicles but you can certainly feel the "string of beads" in there, if they are there, once they are about marble size.
It still takes some practice but now I have no problems feeling those lumps in the belly.
