What I would do is have you BD that 4th or 5th day after your last dose of Femara just to cover you for a couple of days, and start OPK as well. Then if you do end up getting another positive within 2 days, stick with the attempt you have had. If 4 days or longer, then have another attempt. If you are in the middle (3 days) then if you want a higher chance of conception but possibly lower chance of pink, have another attempt. If you prefer higher chance of pink but lower chance of conception, stick with the attempt you've had.
If you prefer to do e4d that's fine too. But keep in mind you don't have to get THAT OCD about the e4d pattern. The point is simply having regular unprotected sex that's at least 3 days apart (so Monday/Thursday pattern, not those days but that many days apart). So let's say hubby is being stubborn and it gets to be e4 or 6 or even 7 days. STILL have attempt! There is no sway magic to the e4d pattern, it is fine to have the attempts farther. It will be lower odds of conception, of course, but it does NOT sway blue to do attempts farther apart!!
