Preeclampsia help??

Trinity

So I’ve had a headache for about 4 days. It doesn’t go away with Tylenol or laying in my left side. My last few blood pressures were above 140 but the bottom number was good. I’m gonna go have it taken again by the pharmacist and if it’s high I’ll call in. Is it something I should be worried about? My doctor didn’t seem very concerned by the high top number. Why else could I be having such a strong headache?
