Hello I'm new here

My husband and I have been trying for 3 years for #2 no luck. We've tried clomid and some other pill as well. My last period was in August, I was supposed to start last week Tuesday. No period, no positive tests, no symptoms. 7 days after ovulation I had lite spotting for 1 day, didn't want to get exited. Saturday it will be exactly 6 weeks since my last period. Should I wait to 9 weeks and call the doc if I don't start or get a positive to get blood test? I don't know what to do. TIA
