Endometriosis & PCOS - a Fertility Problem?

Rheagan
Hey lovelies. 
I wanted to talk about endometriosis and polycystic ovaries as it's an illness I've suffered with for almost 10 years now.
I conceived my 5 year old very easily regardless of being told that I never would, and my pregnancy and birth were very textbook and I had no complications! I'm now trying to conceive my 2nd baby, and I worry that there may issues this time as I've since struggle after having my 5 year old. Has anyone experienced endometriosis or any fertility impacting illness in the past? 
Please do share your stories :) Xx
