But what happens if your having sex every other day? Never count it? The only way we got pregnant the first time was having sex every day or every other day for a month! OPK's never really worked for me. With our 1st it took 9 mo of trying.
In my experience, the day after sex is usually when the sperm makes it's second appearance, I wouldn't count it.
What I have read, is that you should not check your cm the day after sex, Because they are alike.
