Is this pollen allergy?!

I’ve noticed that since this morning, when I woke up I had a stuffy nose and itchy eyes (this happen only the morning when I had just woke up and also the night- not during the day), with May starting could this be pollen allergy/hay fever, they usually starts around this time every year for me?

Could be, but for me it is all day long.

How do u deal with that, any remedies for it?!
