Possible endometriosis?

Just looking for some advice... I'm 21 and for the past few months I've noticed pain/pressure/discomfort around the time of ovulation and I also had quite bad period pains last month. I was on the pill for a year and a half and came off it this time last year and that's when I first noticed this weird 'ovulation' pain but it isn't on one particular side, it's kind of all around the pelvic area. Does this sound anything like endo? I've been referred for a scan (got to wait 3-4 weeks)
