Gotcha! :) Doc was wrong on that as you obviously know - you O an average of 5-10 days after your last Femara dose and NOT on CD 14. Some people O even later than 10 days after their last dose.
There are two different methods we use involving BD every 4 days. One is just BD unprotected every 4 days, and then the other method is doing BOTH every 4 days plus then adding in one additional attempt at positive OPK (this is better odds of conception but possibly lower odds of pink - but remember, you have the Femara working for you too!!) In that case, yes, you would BD every 4 days and then add in that attempt at pos OPK no matter what. Even if it's the very next day. Do NOT try to "time the attempts" to fall on a certain day. That has never worked and just causes people tons of stress, plus doesn't up odds of conception anyway (since you end up really just having one attempt that way most of the time). Just BD every 4 days and then add in the attempt at pos OPK.
If you think that doc will re-up your Femara (and I do urge that you mention how the timing was off that month due to hubby's work schedule) then in that case, if you really feel like you want to give it a month with just e4d, then in that case skip the pos OPK attempt, and just BD every 4th day. Don't try to make it come out a certain way. That is lower odds of conception but may be better chances of pink.
