Sinus issues!

I had a miscarriage back in 10-26-14. I was 15 weeks. The whole time I was pregnant I had sinus issues. I have been TTC since then. I had my last period on 12-3-15 and had a urine pregnancy test done at my doctors on 1-13-16 which was negative. However I still have not had AF and now I'm peeing all the time and having sinus issues. I'm scared to test and get a negative again. I was wondering if anyone has ever had this issue and been pregnant.
