No BCP. I think 35 TI cycles with nothing should be a hint. I first consulted with Dr A after I was told to get a lap for an endometrioma from my old clinic. He said no. Even if you remove every bit of visible endo, there is microscopic endo that releases toxins and messes with the egg. You've probably seen this blog:
I also have the antisperm antibodies and DH low morphology which may have played a part. I think endo definitely had a part in why I couldnt ever have TI success.
BUT I do need to get Mirena or something because oh my goodness...
GL to you!!!!!
