Pregnant?

Hey everyone. So I posted last week about this but nothing has changed. I have been experiencing many pregnancy symptoms since a week before my period was supposed to start, 11 days ago. The day I was supposed to start I began spotting brown thick discharge. The next day was slightly red but it lasted 2 days and I've never just spotted before. I've taken over 7 tests and they are all negative. I go for a blood test tomorrow but I am really hoping to be pregnant. Anyone else have negative tests and still turn out preggo? Thanks!
