Clarification: This is NOT how many NEW messages I have had at ONCE. It is my TOTAL messages since I have joined Scratch. Tip to find out: Instead of counting ALL your messages (which would take very long), press ctrl or command and then 'f', to get search and replace. Scroll down to the bottom and press 'Load more'. Keep doing that until you reached all your messages. Then in search and find, search the word 'ago'. Keep track of that number, and then search 'last'. Add the two numbers together! This works because ago is put for every time amount on every message except for one. So, for example, '2 minutes ago', '2 months ago'. And the exception of 'last month', so that's why you search 'last'.
