There are two options to check those easily:
Jochen website
https://jochen-hoenicke.de/queue/#BTC,2d,count
Or mempoolspace but you need a few extra clicks:
https://mempool.space/graphs/mempool#1w
On the top left there is a button, you click it and then click "count" which is disabled by default in graph and you get this:
The white line is the count of transactions and between January 13th and 14th it grew by 100 000 transactions sitting in the mempool!
That's what Don Pedro Dinero was talking about!
Very useful knowledge, thank you for the explanation and I appreciate it.
I admit that I am still a beginner in Bitcoin transactions and this is a very valuable experience.
I continue to study every step of a Bitcoin transaction and this makes me think several times to understand it.
This means that it is very clear that if 100,000 transactions run into the mempool, the results will definitely congest the Bitcoin Blockchain network and the results will provide very expensive transaction fees.
Hmm, it's the price you pay for one inscription, once! The one I mentioned is this:

Okay mate , for this answer i'm still to check this link website and still study.
But do note that inscriptions differ, that's a text inscription, people are inscribing everything in the chain
Bitcoin Magazine inscribed this:
https://www.ord.io/1290742
It's a 992.44 kvB tx that occupied nearly an entire block at a fee of 49,622,200 sat$ / 13,558$
Haha , hey Dude , this price 13,558 USD very crazy for 1x incriptions.
Indeed, cryptocurrency has a lot of crazy people looking for oddities in their lives, this really makes me think and is beyond my thoughts.
So, i have a bit question again . What could make it expensive to charge this Bitcoin Magazine in one Inscription??
Can you explain to me again , thanks

I also sometimes use https://mempool.observer/
Well , this website link made me think simple , i like this informations and its very easy to check it . Thanks Mate
