Headaches...every single day, sometimes multiple times a day.

Is this normal?! I'm 16 weeks almost 17weeks. Been getting headache more frequently the last month or so. Everyday I get a dull aching headache. I take Tylenol but it doesn't always work. I use to be able to take anything and it worked fine. Now it's a daily battle. I'm tired of the headaches and tired of taking Tylenol to try and relieve it.
