every 4 day method is actually having sex, not just releasing. Unprotected sex every 4th day starting after AF ends and continuing on till you are 100% sure you've ovulated, even if that means going on until your next period starts.

You can do the e4d either on Monday/Thursday (this is better odds of conception, but possibly lower odds of pink) OR on Mon/Fri (this is lower odds of conception but possibly better odds of pink.) Do whichever pattern meets your needs better.

If you start off doing e4d then DO NOT add in another attempt at positive OPK. That is for later on, if you have trouble conceiving after several months.

E4D may be ~slightly~ less pink friendly than one attempt (although we do not know that yet) but it is simply an easy way to have one attempt. This is because the odds of conception on O-4,5,6 are practically nil, and so you end up having your next attempt O-2,1 which ends up being one attempt (since the earlier attempt can't make it that long). Even O-3 and O Day is really one attempt, because if there is anything left from the O-3 attempt, it will have fertilized the egg before the O Day attempt can capacitate, and if the O-3 attempt is dead and gone, then the O Day attempt will have its chance at the egg. So either way it's still one attempt really.
