Implantation bleed: Ovulation occurs 2weeks prior to the next menses. Unless you have a long cycle it seems that you have already ovulated before having sex on cd 23 . Neverthelessless if you did ovulate that late you should expect you period on jan 24-27th, with implantation around jan 17-20. Spotting earlier would unlikely be implantation.
