I won't go into the whole back story because it's not relevant to my current situation, but DH and I have been TTC for two years now and I've been put on luteal phase progesterone, which I am taking from the day after I ovulate for ten days.
So I ovulated on CD17 and finished taking the ten days of progesterone on Wednesday. Since Monday (so nearly a week) I have had light spotting, mainly brown or pink and literally one or two spots per day. AF is due tomorrow but there has been no sign of the spotting increasing- in fact, it seems to have diminished. My BBT has also stayed high, in fact it increased this morning- but I am getting BFN even on FRERs 
Can anyone advise what this might mean? Could I still be pg despite the spotting? Today I am 14DPO and very confused!
