Super late. spotting. negative.

Hi! My boyfriend and I have been ttc for a little over a year. I have not had my period since July. Of course I've taken countless of test and all have been negative. Now it's been about 5 days that I have been spotting. I once again took a test and of course it says negative. Could I be pregnant or having a miscarriage? I'm scared to go to the doctor and have them say I'm not pregnant. 😔
