Feeling Strange

I have had such strange things going on lately. Swelling on and off where I feel like my ovaries would be (on both sides of my pelvis area). Exhaustion. Crying spells. Extreme bloating. Sharp pelvic comes and goes. Negative pregnancy test so that's not the case. Any ideas on what it could be? I've considered ovarian cysts since I have have them before. Possibly a hernia. Anyone gone through this who may could shed some light??
