Headache normal or concerning?

Sarah

ill start by saying I have been diagnosed with preeclampsia and I am on medication for my blood pressure. I've had a headache since I woke up this morning. I took tylenol, a nap and had some caffine. the headache isnt extremely painful just annoying. my blood pressure has been up and down today. I've also had some BH contractions and some sharp pelvic pain today. is this just a normal headache or something I should call the doc about. I have a doc appt tomorrow for one of my 2 times a week  nonstress tests. I will mention it during my appointment tomorrow.
