I know that the EWCM shows ovulation time but is this the only time of the month you can get pregnant? I understand sperm can survivea few days so you they could still be there at optimum time, but if you BD after ovulation is it impossible to get pregnant or just unlikely?
You also get ov cm after ov so best not to get it and think 'Oh i best bd now' Just do it as much as can or at least everyother day before and on day of ov.
Some cervical fluid after ovulation is possible because the corpus luteum, though its main function is to produce progesterone, produces estrogen in small amounts. This may cause you to see some fertile-looking cervical fluid, even after ovulation.
If your temperatures and other signs show clearly that you have already ovulated, then you can be confident that you are no longer fertile. It is also not uncommon to confuse semen and eggwhite or watery cervical fluid. Some women also notice some fertile-looking cervical fluid just before menstruation.
However, if your chart does not show clearly that you have already ovulated (with a clear and sustained thermal shift) do not stop having intercourse. Keep on considering the possibility that you are still fertile as long as you see fertile cervical fluid to make sure you don't miss a chance to conceive.
jamiesam .. didn't mean to be brusque .. keep seeing that 14 day thing (and responding) and I've also heard it from a GP (who really should know better) and for an average number of people its a helpful guide but for most it can actually get in the way of conceiving / not conceiving
