Could this be a sign of pneumonia or something more minor? - what is pneumonia more condition_symptoms

OK, so these days I've been sick with this cold. i cough with phlegm (yellow), long sleep, shortness of breath and my chest hurts when I cough occurs for about 3 days now. People said it could be a pneumonia, but I do not know. I wanted to try to let go, but I think the cough worsened with more mucus. No idea what could be? In 18w5d pregnant, I can no medications.
