Endometriosis help!


I was recently diagnosed with Endometriosis last week. I’m scheduled for a laparoscopy on June 11th. I’m about 5 DPO and yesterday and today I feel extremely nauseous. I know it’s too early for pregnancy symptoms so I was wondering if the nausea has something to do with the endometriosis. It comes and goes in waves throughout the day 😭 Does anyone have experience with this?
