Slight spotting

Andee • I`m a 31 year old mother of 2 great daughters and 3 fur babies. Ttc #3 for me and #1 for my DH.
I39m 13 dpo now and have been having all sorts of symptoms (abnormally cranky, more than with PMS, breasts are sore, and nauseous). I thought this would be my month. Tonight I went to the restroom and had some slight brown spotting. Is this normal, or am I out? AF due on 7/7.
