Hi.My period is 4 days late. I usually have ovulation one week before period. More than one week ago i started having sharp pain in my ovaries from today in my uterus also. Since I m late i went to my doctor today with hope that he ll see on ultrasound that I have blood inside my uterus and will tell me that soon i ll get my period. He told me that I have it and I could get it in not more than 7 days from today, but also that it could possibly stay there if i m pregnant. And if I don t get my period in one week he said he ll be able to tell me if I m pregnant. I saw the photo on the computer and it looked like a shadow in the middle of my uterus. It was not very small so shouldn t that mean that is the blood for my next period? Shouldn t pregnancy look different than blood waiting for period?
