Discharge increase? Normal???

Okay, this is my chart according to glow and it's right on with my opks. I had a surge on Wednesday. Unfortunately we could only bd on Sunday and Monday as hubby was out of town. Well now I'm having slight cramps and a huge amount of creamy white discharge. Is this normal? Usually after ovulation I'm as dry as can be. I didn't think we bd enough for this to be our month but read this discharge can be a sign of pregnancy.. Anyone else have this
