I was woken up around 3:30 this morning with a horrible headache. It's weird though because it's just on the keft side of the top part of my head. I'm 6w3d pregnant. I know headaches can be common in pregnancy but does this one sound normal or should I call the on call dr? Maybe see how I feel tomorrow? It's worse when I sit up or stand. Anyone else have anything similar happen before? Trying not to freak out. ? I took Tylenol at about 8:30 this morning.
