I had horrible Endo in my 20’s. I took 4 advil every 4 hours for 4 days straight & I am a petite gal.
Tried it all: laser lap, the pill, Lupron, depo & IUD. I found anything hormonal made my me flare up with cystic acne & be not such a nice person. 
The Endo got better in my 30’s (I have absolutely no idea why) & I had a uterine ablation. No more period, no more cramps, no more PMS. The only regret I have is I wish I’d done it sooner.
If you decide to get one: DO NOT let some male GYN tell you they can do it in the office. BS! Any U/S tech can tell you about all those types of jobs that are botched. Go to a female doc who specializes in this, will use twilight sleep sedation & has high success rates.
Good Luck!
