9th week pregnant having headache and feeling tired. light pain some time not regular in abdomen.should i go to meet doctor or its normal?

Early pregnancy: Most of these symptoms are pretty normal for early pregnancy. However, its at least time to make a prenatal visit and start prenatal care as some OB providers can take 2 weeks or more to get in to see. But nothing here sounds like an emergency in general.

Tylenol (acetaminophen): Usually doctors recommend tylenol (acetaminophen) for headaches and minor discomforts during pregnancy.

Probably: These types of symptoms can be part of a normal pregnancy. If you remain concerned, it is best to call your doctor.
