Hello ma am. I would first advice getting yourself examined physically by a doctor, followed by a blood investigstion to check on your serum hCG level; to rule out anpossible pregnancy that could have resulted in a miscarriage. Once this is ruled out, your doctor will have to consider other causes for such a presentation and examine with the help of a transvaginal ultrasound scan, bimanual examination, speculum examination, pap smear, among other investigations. In the meantime, please abstain from all forms of sexual contact if your are indeed sexually active. Best wishes.
