The same as when one is not... its not a sign of anything. During the TWW you will have creamy/lotiony CM (most women will at least) regardless if you are pregnant or not.<br><br>
Some get EWCM again a day or two before AF is due (or even around 6dpo) due to a rise in estrogen, but thats neither a sign of being pregnant nor a sign that you are not. You cant tell anything by CM except that you may be gearing up to ovulate.
CM in pregnancy doesn't change until quite a few weeks in... I want to say for me it was around 10ish weeks. CM is not an accurate indicator of early pregnancy at all. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile"> Neither is cervical position.
