Hi
Sorry I haven't had any births as of yet but your endo story is similar to mine. Don't lose hope. Ask your surgeon to preserve your fertility.
I got diagnosed with stage 4 endo and die when I was 34, like you, I had a frozen pelvic, my left side tube and ovaries where attached to my womb, my kidneys started to get tangled, my bladder had endo, my intestines all covered (so much so that my doc said I might need a bag temporarily) and I had adhesion on my parts- all in the muscle. I hadn't met my husband then, so there was no chance of kids before. My surgeon worked to preserve my fertility.
I helped myself by doing caster oil packs for the month before my surgery (that made such a big difference and helped so much)
My surgeon suggested going on a medically induced menopause. Which I did. It helps when they cut you open.
Operation was a success, although I did lose my left tube.
I got married a year later. I thought i wouldn't conceive naturally, but within a year, I have done 3 times. Unfortunately, first was a cp, and second was a mmc. I'm currently 4 weeks pregnant and praying I have a healthy baby.
So there is hope, I know it doesn't seem like it (I felt like I lost my chance of being a mama when I had been diagnosed) but keep faith and keep positive and do the best you can for yourself.
Also, look at vitamins that help with endo and fertility. I take vitamin d, iron, folic acid, dha. Was taking coq10 and angus cactus but stopped now I'm pregnant.
Good luck, I pray it all works out for you, dont lose hope 🙏
