Cramp advice please

SD

I had a hysterectomy (left my ovaries in) in Oct 2017, due to heavy constant bleeding. Diagnosed in 2011 with endo by a different Dr.

Anyway, since Monday I have had this ache low in my pelvis. Like a bad period cramp, particularly on the left side. My gynae is off till mid June due to a surgery he had. But he was uninterested in my endo questions previously saying my pregnancy would have cured it.

What could these cramps be? I've been taking pain killers, meds for possible uti and also am not constipated.

Should I wait a few more days or go see my GP? Or a new gynae?
