I am 27yrs old, have never had children and have been on the pill for about 12years. I went off of the pill in Jan- May 2007. While off the pill my cycles were all over the place- ranging from 30-45days in length, lasting about 7 days or so. SOmewhat heavy bleeding, and some pain- not too horrible. Because my cycles were so crazy- my doc sent me for a transvaginal ultrasound and a pelvic ultrasound. It came back "endometrium slightly prominent". Now, the day after the test- I got my period. Is there any chance that the test could have shown that because my uterus was full of blood, or do you think it could be something more? I have to go this Friday for a repeat. I went back on the pill and am on the second pack- do you think it will still show abnormal? Is there a chance it could be cancer or would that show up in the ultrasound? Could it be endometriosis? When I am on the pill, everything is good. It is just when I am off of it. When I was off of the pill, I also experienced other symptoms such as pain sometimes during sex, shooting pain up my rectum(once in awhile), abdominal bloating from time to time throughout the month.Do you think it was something else, for instance, a cyst or tumor- wouldnt the ultrasound have said that? Or do you think it could have been just because of my period coming? If that is the case, because I am on the pill now, my new results shouldnt show that right? Doesnt the pill stop it from building up? Thank you so much!!!
