A lil confused. PLZ HELP

Well after about 4 yrs of ttc i finally decided that it was time to take a break and decided to get on the pill. My husband and i decided to get a way for a wkend and i forgot to take my pills which also happened to be my most fertil days. We did have unprotected sex and when i got home i started taking my pills again. But i started my period early and now im having brown/pinkish spotting only when i wipe. According to my calander its been 12 dpo. My question is, can i be.pregnant even though i got an early period a few dpo???
