Good afternoon, I’m 5 weeks and 5 days pregnant. At the gynecologist’s exam she said the pregnancy is confirmed and the uterus is soft — what does that mean? Sometimes I feel a pulling sensation in the lower front left side. I have problems with bowel movements. There is light green discharge; it started with a yeast infection when I became pregnant.
