Dont know whats happening with me


So i haven't gotten my period yet i still have two more days to go. Yesterday i slept all morning because i had to work in the afternoon and i was feeling fine. A couple of hours at work and boom i start throwing up. I had only ate once that morning prior to going to work and nothing for the rest of the day. All night i had been throwing up and having diarrhea And i still dont feel good. Idk what is going on with my body because sometimes i get sick but i never get this far. I been with my man for fours years and i started having doubts about us if we can concieve and its been four years of nothing and now i think something that im afraid to say might be happening. I just need confirmation. Lol
