Talk to Gynecologist on Headache And Pregnancy

I am having pain above my left eyebrow everyday after breakfast , I had flu, cough and fever 2 weeks before, i havealready taken 2 courses of antibiotics cefspan and lcyn for 3 days each as recommended by doctor. Last week I got tested for beta hcg because of missed period and i am 4 or 5 weeks pregnant too. My headache gets okay once I take steam but worsens if not taken steam. i have alot of phelgm coming out too, two to three times there was blood in phelgm. My appointment with gynaecologist is is next week.. Which medicine can i take? What’s the reason of headache?
