Several patches of egg white fluid with no clear thermal shift may mean that you are having an anovulatory cycle or delayed ovulation. You can have "fertile-like" cervical fluid and still not ovulate. If you have several cycles that show this pattern without an associated thermal shift, you should ask your doctor to help determine whether or not you are ovulating.
If you have several patches of egg white cervical fluid and a temperature rise, then your ovulation was probably delayed due to some external reason. As long as ovulation is not already clearly indicated, you should still have intercourse at least every other day when you see egg white cervical fluid to make sure not to miss an opportunity.
