Endometriosis

Advice please- When I was around 13/14 I had the worst period pains. They made me sick and I just had to go home and lie in a ball. I was eventually put on birth control pill by my doctor at the time to advised this would help, and it did dramatically. Fast forward to 28 and I've been off birth control for 1 year. No pains at all when I'm getting my period just usual minor cramps. I'm now worried that I've had something like endometriosis back when I was younger and now this could be the problem I'm struggling to concieve. Would I still be getting major pains each month if I had it? Can you grow out of it? Any advice would be greatly appreciated. Oh I've also had 2 chemical pregnancies.
