Hi Maya
Endo is a strange thing, I think the problem they have with determining it's cause & cure is that it is different for everyone.
I also have endo. I only found out through a lap when I'd been TTC for a year. I also had absolutely no symptons at all, and I had a severe case!
I ended up with my DD using clomid & a trigger shot for O.
Now, I get the symptons of endo, strange and getting worse. I've had 2 more laps and now having IUIs. I still feel very confident that I'll have another baby, even if it means getting a bit of help.
Just keep positive & just know that it will happen.
Good luck.
