snow: if BD then perhaps might wait longer if you want a for sure answer lor... cos after BD, let's say you BD just before you O, the boys can survive up to 3 days inside you... so let's say fertilisation takes place 3 days later, then still got implantation and all, so if you don't want a false negative, maybe 3 weeks after BD should be a safe bet bah... that way, if BFN, then most likely is BFN, won't be BFP liao... cos the spermies cannot survive so long one.
aiyoh, this little one of mine, cannot leave the rabbit alone... poor fellow sleeping she also go and kachiou... if they can talk they sure say, how come today you come home so early? go away! let me sleep in peace!!! hahaha
