i’m 26 weeks pregnant and for the past 4 days i’ve been having the most awful headaches. they start from underneath my eyebrow (it’s so sore there) and they extend upward to my head. but only on that side. tylenol takes it away sometimes but they’ve just been reoccurring throughout the day for the past 4 days. does anyone know what could be causing this? especially under my eyebrow? and remedies?
