When I speak English, I tend to put glottal stops in front of words that start in vowels. Is this normal in Russian? Is "это" pronounced with a glottal stop in front of it, or am I pronouncing it wrong?

I also want to put a glottal stop between vowells, so I'll say "аэропорт" with a glottal stop between the 'А' and 'Э', as well as one before the 'А' for the reason I mentioned in the previous paragraph. Is this wrong?

Спасибо!
