+ opk when do we bd and when will I O?

[Mrs. Burch]

I got my first + yesterday, CD16, at 8am and again at 12pm then so far this am, cd17, at 7 it is still +. We have been bding since CD12 ED. This is our 2nd cycle ttc and I never tested the first cycle. My temps have been kinda crazy this cycle, I haven't shot up yet, my temp, so how much longer do we need to bd? I have had watery cm, no Ew which I didn't have last cycle either. Thanks in advance for your help and baby dust to everyone. Hope you all get your BFP for Christmas!!
