I’ve recently found out that there was a cyst on my ovary and it ruptured. My period is 5days late, is it possible that I’m pregnant? Please help

Ovarian cysts. Every month when ovulation occurs, a "follicle cyst" ruptures to allow the mature egg to be potentially fertilized. Sometimes when the egg is defective, the fluid in the follicle makes the cyst larger, and the eventual rupture produces more pain. To be certain you are not pregnant, wait a week and get a serum HCG test from your provider.
