I am cd17 of a 28-33 day cycle (varies). BD so far day 11, 15, 16, 17 (today). When I went to the loo after bd today and wiped (having lay with bottom in air for 20 mins first) there was amongst the icky man stuff a bit of blood. I suppose you could describe it as like a blood spot in an egg, but bigger. I wondered if this could be implantation bleed if I had conceived on cd11 - any later and it wouldn't have implanted yet, or if the blood just one those odd things the body sometimes does. any thoughts? hope this makes sense.
