Anyone experienced this before??

Have been trying to conceive for a while now and this month is very different. Today is 7DPO. And yesterday still i had heavy EWCM. Today is like it completely disappeared. A bit of s sticky CM this morning when i woke up but nothing during today. Like dryyyyyy. In the TWW now during luteal phase. And the only differenceive had this TWW is breasts are more sore than usual during this stage. Sometimes just throbbing whole sitting at my desk. Is this a sign AF is on her way or is there still hope for a positive. Not sure whem to test for a possible VVFL so just thinking on waiting till my period is due. Any help?
