Help me. Slightly freaking out here. 17 wks pg with twins. Had a bad sinus infection that freaked out allergist and I was on 2 rounds of antibiotics and 2 rounds of steroid. I have... (more)

been battling this massive all over headache for 5 wks now. I thought it was pg related but when I was diagnosed w/the sinus infection she said it was that. Now, the headache's back for 48 hrs and going strong. Won't go away w/Tylenol. Called ob. He said it sounds like sinus. Called allergist. Dr on call called and was an asshole and said call ob doesn't sound sinus. Meanwhile last week allergist wanted me to get a cat scan but was waiting b/c of pg. I told ob that and he said cat scan was to probably rule out a blood clot!!!! and an mri would show sinuses... WHAT DO I DO? Flying tomorrow and panicked about a blood clot.
