What Causes Intermittent Period Like Pain And Cramps Without Actual Periods?

I am 32 and had my second c-section 7 months ago. My period returned after eight weeks and had been regular until a couple of months ago. I have not had a period for 7 weeks but have had cramping and pain in my abdomen and pain along my c-section scar. The pain and cramping is intermittent feels a bit like period pain but still no period. It is starting to affect my sleep. There is no possibility I am pregnant. Have been passing lots of clear discharge of and on for last 7 weeks.
