I am 9 week pregnant and have 22mm23mm thick walled anechoic cyst on my left overy and a lot of pain in my stomach for few weeks on and off but no bleeding is this something to worry about?

See doctor: If you are 9 weeks, you should be able to see a doctor and have an ultrasound to make sure everything is okay, showing a baby in the uterus with a heartbeat. If the ultrasound looks good, try not to worry. It is normal to have a cyst on your ovary that ovulated to make the baby - it is called a corpus luteum cyst and it is what keeps the pregnancy going until the placenta takes over at ~ 12 wks.
