Cramping in lower pelvic and back

Brandi
I had lap done back in Feb and that's when they diagnosed me with endometriosis stage 3. Yesterday I began cramping really bad. I'm 6 dpo. I never had any cramping till after the surgery but this time has left me curled up on couch. I'm keeping fingers crossed we'll get a positive this month. But is this normal or any insight would be great.
