Wait for the positive OPK, then have attempt that night, again the next morning, and again the same night (so on the second day, have 2 attempts that day if possible). If your husband can manage, have one more attempt the following day, and then every other day for a few days. But it's really the three attempts in a row that counts.
If you don't believe in timing (many of us got opposites using timing, so it's easier for some people to give up on it) then have sex unprotected every 2-4 days when out of the fertile window (exposure to more sperm may help boost your fertility and make you more blue friendly) and then in addition to that, do the OPK and have the 3 attempts (night of pos OPK, again the next morning and again that same night). This is very much how I and many others got our boys!!
