I am concerned about having this nausea. I've been feeling sick to my stomach for a little over a week now. Just like another person's post, it is almost like morning sickness, however I feel sick in the mornings, it gets better mid morning and comes back again late afternoon. I have read many a website that says one of the symtoms for a cyst is nausea, but the doctor said that he didn't believe cyst cause your stomach to be upset.... Is there a possibility of a tubal pregnancy even after you have had a hysterectomy and only have one ovary and tube? And if it were a tubal preg., would it show up on the ultrasound, or could the cyst be blocking the view of the ovary and tube? I don't know....I am just sick and tired of being sick and tired! I am trying to be thankful for the good news I have gotten, but it is hard when you still don't feel good.
