Hi Doc, based on my transvaginal ultrasound , the OB-Gyne says that I had a minimal free fluid from cul de sac. Is it normal? Im married and i want to have a baby . But this bothers my mind about the minimal free fluid in cul de sac. My LMP was last Dec. 30, 2011 until Jan. 1, 2012 . I had my ultrasound last Jan. 6, 2012.
