In june i had two periods. The first one started on June 11th, lasted about 6 days. And in the days leading up to the second one I bled during sex. On June 28th, the second one started and lasted until July 17th. It was horrible to say the least. Ever since about two weeka ago, during sex when he is thrusting in, i feel this sharp pain in the lower left side of my abdomen. Basically right where your paintline comes to if you wear low rise jeans. Its only during sex and only when he thrusts in. Its painful. I still haven't gotten a period. Im not sure whats going. Im kind of worried.
