Spotting

ambur
I've never spotted before in my life. First day of last Af was 10/30/15. I've never been regular having cycles up to 40 days next predicted AF was 2/1/16. Hubby and I have been ttc for 2 years with no luck. This past week I've been having very very lite spotting thinking AF was going to show up with nothing! I took a test before the spotting started when AF was due with BFN. Anyone have any advice? I go for my first Pap smear today
