New syptoms?

I'm having a slight pressure in my lower abdomin, nausea, troubles getting comfortable, a burning sensation in my stomach, and getting really hot... I'm about due for my period. Just wondering if this is normal, because I don't remember feeling like this before. Can you get new symptoms as you get older? Also, slight headaches here and there.

I'm not expecting anybody to be an expert, I'm just asking for another's opinion.

Thank you.
