Phlegm in cough

If you have a cold then you will phlegm and if you have phlegm then you will have cough. Whenever you cough there is a good chance that you bring out mucus. Sorry if it sounds gross but it will happen. The cold will usually subside after a week and the phlegm will go with it. You can take a few medicines to speed up the process. If you have blood in the mucus then you need to get it checked. The color of your phlegm will depend on the problem you have. It might be green or yellow depending on the situation.

Yes it is normal. Technically, it's mucous, but when mucous becomes congealed and visible it is considered phlegm, the product of your mucous membranes attempting to fight an infection of sorts--and it is good for you. Phlegm is differentiated from other mucous in that it comes from the lungs rather than from the nasal passages; though, post nasal drip, a common symptom of colds, flus, sinusitis, and inhaling other irritants is often the cause of a phlegm like build up.
