I experience lower left abdominal pain with vaginal discharge (clear sometimes, sometimes with very little blood or clots, as seen during periods) every 2-3 months of not every month. This usually happens around my mid menstrual cycle. It's dull, stabbing pain that increases with time and passes away on its own. With this, I also experience increased flatulence and the pain lasts for hours and hurts even more with movement. I just usually wait for it to pass. I'm wondering if it's something serious. I don't bother going to the doctor since it passes within hours, sometimes it also lasts upto half a day. Help and thank you.
