ANYONE KNOW WHAT THIS COULD BE?!

The sides of my lower abdomen/pelvic kind of area keeps having random sharp pains, lower back is killing me! (Not like cramps) my head is pounding constantly, my eyes hurt when there’s too much light, I’m nauseous, shortness of breath and there’s more stuff that I’ve been recently feeling but I don’t have the energy to type anymore. If anyone has a clue as to what this is please let me know. I’m a bit scared
