Spotting

First cycle TTC for baby #2! I had spotting 11 and 12 DPO figured it was just my period coming early, (bummed) I have gotten several BFN. The spotting was brown/pink at first but there was small amounts of red blood yesterday but I wore the same panty liner all day so not a lot. Woke up today 13DPO without the slightest trace of blood. No blood/spotting all night. None so far today. Any ideas what’s going on?
