Why am I having sharp pain in left lower abdomen?

Hello doctor,

I am 31 years old female, 5'8", 175 lbs. Three days ago I started getting a really sharp pain in the lower left abdomen. It came on sudden and was gone within seconds but still bad enough to have me doubled over in pain. Thought it was related to period that was due following day. Happened on and off all day. Next day period did start as expected. Normal flow, normal cramps, etc. Then the sharp stabbing pain came back. It is stabbing in a very precise location, down and to the left from the belly button, kind of in-line with the hip. It was radiating hellfire to my low back, groin, thigh, hip, and left flank. I was on the floor in pain for four hours before it faded away enough for me to even stand.

That night it happened again waking me from sleep. Lasted for hours, stabbing in the same spot, burning pain spread to the other areas. Later that day my toddler laid across me and his elbow got that same spot and started the pain up all over again but it only lasted about an hour. The area is very tender. I still get the brief stabbing pain when walking or coughing or bending over. I am thinking it is a ruptured cyst. I have never been diagnosed with one before but I think it fits the bill. But can they rupture multiple times within days? Is it likely to happen again? Could it be something related to period or just coincidence it started at the same time? What can I do at home for it, since I am unable to go in to see a doctor?
