Thank you for the intake.
I am concerned about two things here mainly.
That this group of symptoms could signal that you are possibly pregnant, even if you just had a period on the 22d of November. While it is less likely, it is still a possibility.
The other thing is diabetes. Diabetes is accompanied frequency of urination, feeling tired, and feeling hungry. The blood sugar and frequency of urination can cause you to become dehydrated and to get headaches.
If you go to your physician for an examination and diagnosis, he or she will most likely at least do a urinalysis or blood test to rule out PG as a matter of routine. While I think it is more likely than not you are not pregnant, it is still a possibility.
Please be advised that this does not constitute a definitive diagnosis, but merely reflects what the combination of symptoms you presented appear to be most likely caused by.
It takes a physical examination, blood and urine tests to confirm this or any other condition.
