Cough and cold persistence. Basis.

Hello., I have donated blood on the 10th of this month, until then I was active, regular eating, etc. After donation, drank whatever they gave, usually I don't drink those. Then I travelled in bus, ate well, drank fuilds well, etc. Took rest, no strenuous tasks for the next 24-48hrs. I caught cold, severe cough, and it's thunderous cough with phlegm mostly. I was not able to eat well in the initial days, now I'm eating, but not back to original diet routine. I also notice in the last few days the eyes are discharging something white on the regular daytime, if its the next day, it's more. Kindly advise, whether it's something to worry or can be taken care. Note: the blood was extracted by a nurse who is just starting to learn how to prick and extract, and she splashed my blood all over my hand, her shirt etc. I have donated blood several times in the past, never faced a situation like this, not able to report to office on a regular basis.
