Hello, with endometriosis
there are hormonal
changes as well as anatomical changes in the body,so just for the reason that follicle had ruptured and egg was release need not mean everything else is alright,a lot of factors come into play for a normal pregnancy
,so my advice would be just don't worry and be stress
free,continue the treatment with your doctor and hopefully you will get positive results in a cycle or 2 with GODs grace.
