I started taking the pill yesterday and I have a headache?

It is important to discuss with a healthcare professional if you experience headaches after starting a new medication, especially a contraceptive. They can determine whether the headache is a side effect of the medication or if it could be a sign of something more serious, like a migraine with aura. You may need to consider alternative options and possibly discontinue the medication if necessary. Taking pain relievers like Tylenol may help alleviate the pain temporarily, but it is important to address the root cause of the headache.
