Brown/pink spotting

Amanda • I`m 32. Ttc baby #1. I had a chemical pregnancy in August and a chemical again in February. Praying for my rainbow baby
So my af is due tomorrow. I feel so sad. I thought it was supposed to come today because at 11dpo and 12dpo I had brown/pink discharge only when I wipe and only in the mornings.. Now it's gone... 
Has anyone ever had this and then had a positive hpt?
