lex - it depends on what you are using (kit or monitor) as to what is going on. I use the kit - either the wondfo internet cheapies or the clearblue digital OPK. I have been temping and testing for the last couple of months and this
is what has happened FOR ME:
1. I get a dip in my temps the day before ovulation. This apparently doesn't happen to eeryone.
2. I get a + OPK the same day as the temp dip.
3. I ONLY get + OPKs in the afternoon.
4. According to the package (CB Digi), you only get the surge for a very short period of time (sometimes only like 12 hrs - hence me only geting + in the afternoon and not morning). Your egg will be released in the next 12-24 hrs
(supposedly).
5. I have not gotten pregnant yet.
Not sure if that helps or makes it more confusing - but I definitely think that temping and charting is the way to go. A friend of mine tried for over a year before she started temping and only AFTER she regularly charted did she realize
that she ovulated at a different time every month and not at all during the times that other website "predictors" seemed to think she would. Good luck to you!
