THat having been said if you are not in a hurry to conceive and want better odds of pink you may want to give a full 4 days between (s0 this would be every 5 days instead really) That way there is NO possibility that you have O-3 and O Day attempts (which can of course be two attempts, kinda sorta not really but still LOL). It's all about what you personally want from your sway. Even e3d is a valid method if you want to up odds of conception.
so nutshell version:
If you want to have better odds conception but possibly higher chance of blue, e3d (Sun and Wed. 2 days between)
If you want a good balance between odds of conception while still good chance of pink, e4d (Sun and Thurs 3 days between)
If you are ok with lower chances of conception for possibly a better pink sway, e5d (Sun and Fri 4 days between)
All of them still have the benefits of regular attempts without the stress and effort of opk or temping/charting. :)
