• Miscarriage – Spontaneous loss of a pregnancy before the 20th week occurs in 10 to 20 percent of all pregnancies.
• Pelvic inflammatory disease (PID) – This is a reproductive organ infection. Complications from sexually transmitted diseases such as gonorrhea typically happen after sexually transmitted bacteria spreads from the vagina to the ovaries, fallopian tubes or uterus. Often PID will become apparent only when a woman is trying to get pregnant. At times, there is abnormal vaginal discharge and pain when urinating or having sex.
• Ovarian cancer – Because of the depth of these organs, this cancer is difficult to detect until it has metastasized within the pelvis or abdomen. At this point, the cancer is more difficult to treat and is often fatal.
• Interstitial cystitis (IC) – This condition is marked by chronic mid-pelvic pain. There’s a near-constant need to urinate and pain during urination and intercourse. IC mainly occurs in women 30 to 40 years old. The cause is unknown. • Pelvic organ prolapse – When this happens, a pelvic organ drops to a lower position. At times, this organ can protrude into the vaginal canal. Pain usually originates in the vagina and back and may involve painful sex. It often occurs in older women.
