Possible endometriosis?

For over a year now I’ve been experiencing pelvic pain in my left side which feels like stabbing, pulling, twinge and a deep ache in my lower back. I have also felt weakness in my leg and sciatic pain too. Recently, my periods have become longer and heavier. I always experience pain more when I am due to come on, or when I’m ovulating. I’m noticing more mood swings too. These symptoms are starting to affect my daily life and I feel like I can’t ignore them any longer. For those who have been diagnosed, does this typically sound like symptoms of endometriosis? From what I have read, I am convinced it could be this. I sadly had a miscarriage back in February and I’m now wondering if this could be linked to what it is that I am experiencing. I will be going to the doctor this week but any advice in advance or anyone willing to share there story would be appreciated. Thank you.
