UGHH help

Dating back to two weeks ago: I hard sharp pain in my lower stomach, which wasn’t normal for me. I only started to get cramps around my period but I was no where near starting it.

Later that day: it got to the point where I just laid in bed for two days straight, moving super slowly, I also had diarrhea once.

Since then: I have continued to feel pain (not as severe as the first two days I can still get up and move and do things), I’ve been super tired which is weird, and I’ve had slight nausea.

Yesterday: I lost my appetite, I usually eat 3 meals a day, I ate a meal to get food into my system but i felt fine after eating. Today I completely lost it to the point that after I ate I felt completely nauseated and felt the need to throw up but can’t.

Have you guys gone through this?
