A few months into ttc, I starting spotting starting 7-9 dpo until AF - and now it occurs every month. The first time it happened, my period started (incredibly painfully and suddenly). Now, the same thing happened again! I will spot about 7-9 dpo, it will start to taper off and then BAM! AF. I've heard that is could be progesterone related. Any success stories out there with this problem and using progesterone?
