My husband and I have been TTC for 6 months now, haven’t had any luck. I have been feeling this month might be the month it worked. I am 3 days before my expected period and this morning I had light pink/red spotting. Its gone from that to like medium flow kind of! It isn’t filling pads or anything but it’s noticeable. I don’t know whether or not this is AF or if its implantation. What are your thoughts?
