Your OPKs seem to indicate your are ovulating at the "perfect" time ie. 14 days prior to AF starting is the typical time for ovulation. that 14 day period of your cycle is called the luteal phase. day 17 to 22 sounds perfect for you but personally, I think BDing everyday is overkill. sperm are supposed to live for up to 3 days and some peopel say 5 days so BDing every 2nd day would mean there are some there on the second day anyway.
the other thing is before you started TTC, did you notice any EWCM? that is the best indicator of ovulation. the only thing is that if you are getting busy all the time, it can be hard to tell teh EWCM from "leftovers" IYKWIM. (sorry about the TMI)
good luck - sounds like you are very organised and have it all sorted.
