OMG, I got a smiley face with my OV stick.

This means that I ovulate pretty late in my cycle (or this is a one-off) so gals, can I ask a few things which I hope people can answer:
1) Does this mean I am due to ovulate in the next 24 hours?
2) But my CM has gone a bit dry, no more EWCM. Surely when you’re about to OV, your CM should be at its most copious? I thought I O’d a coupla days ago as had major major EWCM.
3) Maybe this means that actually, BDing yesterday was the best time as had EWCM and OVing imminent?
4) Just texted hubby, saying ‘OMG, I got a smiley face. Get your pants off and get ready for some hide the sausage after work’ and he just texted saying he’s not sure he can cos he’s still hurting ‘down there’ from last night. Which leads me neatly onto …
5) If we don’t BD tonight, will BDing last night be enough? Or ought we try to tonight or tomorrow am?
And finally, I have a 28-day cycle. If I OV on CD17-18, does this leave enough time for the embryo to imbed (but SO sure I O’d yesterday or Wedn, me confused)?
