Ewcm 6dpo???

Kristen • Ttc#3. Currently have a 6 year old daughter and 19 month old daughter. Married to my husband may 2014.

im 6dpo today. O confirmed with opks and temping. Up until today I have had creamy cm after o but today I have had ewcm. Is this just a second estrogen surge or what else could it be? I've also had mild cramping off and on today and been starving all day.
