My left ovary has something called an enlarged cyst that measures about 27x21mm, and I've been having really heavy stomach pains and bleeding during my periods. The pain's been so bad that I feel like throwing up sometimes. My periods are also delayed. Should I be worried about the cyst or all these symptoms, or is there something particular this might be indicating?

Your symptoms could be related to an ovarian cyst. The delay in periods, heavy stomach pain, and bleeding during periods, along with vomiting, are concerning symptoms. I recommend you consult with a gynecologist for further evaluation and management. In the meantime, you can take pain relief medication such as ibuprofen (e.g., Advil) to help with the stomach pain. The usual dosage for ibuprofen is 200-400mg every 4-6 hours as needed for pain. However, it is important to consult with a healthcare professional for proper diagnosis and treatment plan.
