First off, are you doing 72 hr or 96 hr version of e4d?
Need more opinions, but here's mine.
So today is our Thursday. Dtd tonight and if your positive opk is saturday and you O on sunday, then you will have an approximate o-3 attempt. If you add in another attempt on Saturday, then you'll probably have an o-3 and o-1. Boosting conception odds, but less girl friendly.
If you dtd Thursday and your +opk happens sunday then dtd then and that will give you an o-1 attempt and a good one attempt with high conception odds and being girl friendly. I don't feel as a o-4 attempt counts at all.
