Is there a rough time when it occurs?
Due AF in 2 days, started (dark brown) spotting yest, very light pink spotting today. Believe I ovulated around the 5/6th jan (but don't know for def) so think this is more likely to be AF than IB but may be wrong. This is first time TTC so any experiences would be good to hear. I am a total novice and hadn't even heard of implantation bleeding until 3 weeks ago
