What Is My Vaginal Ultrasound Result Suggestive Of?

Went in for my annual ob appointment and had quite a lot of pelvic pain during exam. Dr did vaginal ultrasound also- no ovarian cysts but mentioned an insignificant polyp in uterus and a shadow . Ordered some blood work and pap- waiting on results but what does a shadow indicate and should I be concerned? Does a pap and vaginal ultrasound with blood work typically identify woman-related cancers? He also repeatedly mentioned needing to do a laparoscopy if pain persists. What would the reason be to do this? Thanks- it s hard to know the questions to ask during the visit.
