Headaches in eye??

Ha

I'm 13 weeks pregnant and ive had headaches in my left eye for DAYS like 4 or 5 days. I called my nurse and she called back with a prescription for me to take IF and only IF it gets any worse. I forgot what she said she med was but she did say it can cause problems if i take it when it's not 100% necessary. I don't think I want to take it at all if there's a risk. I took extra strength tylenol, drank lots of water, rested, ate ect. I had high blood pressure and preeclampsia with my son and they have me on baby aspirin to try and lower my risk of getting it again. Any ideas on what else i could do for ny headache?
