I'm just over 17 weeks pregnant and I have pain in my left side of my pubic area just underneath my abdomen. I've had it for over 15 hours on and off and it's like a deep knotting throb sensation. Should I be worried or could it be a cyst on my ovary? All I can take it paracetamol and it's not touching it. I have polycyclic ovarian syndrome so already had 3 ruptured cysts but pain only last few minutes with those when they burst. Please help . Any advice would be appreciated.
