You sound fine, Viola! Just note that in real life, native speakers usually drop the “n” in words that end in /nθs/. Unfortunately, this is hard to find in a dictionary, since no English word ends in /nθs/ except in suffix form. In fact, “month” is the only word in English that has even /nθ/ (without the /s/) in morpheme-final position. The other words ending in /nθ/ consist of two morphemes each (the /θ/ is just a suffix): seventh, ninth, tenth, eleventh. At least in America, when educated native speakers pronounce these words in the plural, we usually drop the /θ/ unconsciously.
