I have miss my periods for more than ten days. My cycle is always regular although I have painful periods due to endometriosis. I took evening primrose oil 500 mg twice a day to increase fertility. I am not doing any protection as I've ttc for 10 years. I just had a failed ivf on july and now i'm wondering why is my periods delay and experience abdominal cramps on the left side. There is no spotting or sort of a vaginal discharge. I haven't done any test as I thought it was too early. I also experience tender breast and frequent urinating. Is it possible to get pregnant with a blocked fallopian tube, hydrosalphinx uterus, adhenomyosis, severe enndometriosis and chocolate cyst or anything worse might happpen. Has anyone here conceive with endometriosis?
