At 32 just realized I am Stuttering during the meeting

At 32 just realized I am Stuttering during the meeting So I am preparing my presentation while I was saying "Linear regression" I was finding it hard to pronounce lineaR Regression that two R is causing me the problem. I did not notice these before I am usually fluent but very slow to catch one between conversation. But now I think it has always been my problem. Do I have any cognitive problems? Should I be worried? BTW English is my second language But i am sure it also occurs in my mother tongue.
