Google do their accouns each month; so if there is over 100 dollars at end of Jnauary, you'll get the payment late in February. Exact date will vary with country.

Did you see this on your login page:

If you have not received last month's payment by the 25th of this month, please contact us using your login email address and include the cheque details of your payment.

So you should get it by 25th February.

That's not correct, the message from Google would refer to earnings from January which should be paid at the end of February but if you haven't received them by the end of the following month ( March 25th ) then get in touch with Google.

If payment in progress appeared on the 23rd February this month, there is no way that Google would tell you to get in touch if you hadn't received the money in your bank two days later, everybody would be writing to them in that case as absolutely nobody will have the money in their accounts by tomorrow ( 25th )

Sorry, you are quite right, I'm in error.

January's payment will be made near the end of Feb, and it's 25th of march before you can complain (assuming you'll need to, which is unlikely).

If I remember, my first payment was a little later than I expected, all since have been like clockwork.
