First and for most. I have not had sexual intercourse. I can assure that. I am although sexual active with my boyfriend.

lately I have been feeling a swelling in my stomach, and when I press down on my stomach, just inside my pelvis, where your body cradles your stomach, i can feel an almost like "lump" off to the side. i sometimes feel a sharp pain at my side too. I also end up bloated, and i can feel my back hurting. I have swollen breasts as well, they just feel much heavier. My period hasn't come, I'm sometimes irregular, but for the most part, I'm usually on time. I find myself going to the bathroom a lot, and when I urinate, i feel a burning feeling. I don't know whats wrong with me.

the last time my boyfriend and I were intimate was about three weeks ago, and during which I may have gotten some of his semen on my hand (sorry to sound like a pervert.) Is it possible that maybe it got on me when i used the restroom later on during the night?

Also, it's been brought to my attention that I may have a cyst. Would a cyst manage to delay my period nearly a week?
