Pregnant?? Help!

I had a miscarriage due to an ectopic pregnancy at about 10 weeks the beginning of August this year. My husband and I have been TTC since then. I last time I had AF was Oct 17th, and now I am on cycle day 35 (usually 28 days for me) I have multiple pregnancy symptoms, but have taken 2 pregnancy tests and they both came back negative. Before I miscarried I took tests when I was 3 weeks late, and they were negative even though I was pregnant. Should I wait a week and then test again? Go to my doctor for a blood test? Or just wait for AF?
