Back pain/ endometriosis??

Molly

I have regular periods with normal cramping that lasts about 4-5 days. I get a lot of dull achy lower back pain with ovulation and like a week before my period. I just finished my period 3 days ago and for these last three days I’ve had the same lower back pain and cramping that’s been pretty uncomfortable. We’ve been try for 8months. Does this sound like endometriosis at all? I’m freaking myself out because this is not normal for me
