Hey, sorry to jump in to this mid-conversation but I just wanted to say, although it can be more difficult, it is possible to fall pregnant with severe endo.
My story: We had been ttc for four years and eventually went through two rounds of IVF treatment last year, both of which sadly failed. Then by some miracle I found I was pregnant in January this year (naturally!) while I was waiting for my third round of IVF! Sadly I miscarried at 12 weeks but I proved it was possible to actually get pregnant in the first place which I suppose is a positive thing. I am 38 years old so age isn't on my side either.
My last surgery was six years ago. I had it to remove a large ovarian cyst that was really bothering me and at the same time they went in with a camera and that was when I found out I had endo. Symptoms improved after that but after my IVF treatment last year my symptoms got unbearable again so I went back two weeks ago for a lap and found out I had stage four endo pretty much everywhere 🙁 It causes me a lot of problems with my bladder too. I feel like I constantly have a bladder infection and constantly needing to pee like something is always pressing on it. So I have been referred to a specialist centre for surgery to treat it all and we won't try to conceive again until after this now.
I know my story isn't massively positive but I just wanted to say you're not alone and also that it IS possible to get pregnant with severe endo so don't lose hope. Good luck x
