I know it's going to be a BFN

Have you missed your period and thought how you could maybe finally get a BFP? The last time I had intercourse with DH it was around the time I was to ovulate. I did not have any tests so I don't know 100% but I had all of the usual signs and symptoms of ovulation. About 3

days after I had very faint pink spotting with a little brown spotting + CM. This went on for maybe 2 days. I'm 9 days late now. Two days ago I had very faint brown spotting again but was very brief. I bought a test to take in the morning. DH's birthday is Saturday and I would be so excited to be able to tell him we are finally pregnant as a birthday gift but in my heart I know it's going to be negative. Feeling down yet still have a glimmer of hope. I just get so tired of this feeling.
