Nauseated !!! HELP!!

Julia

I’m what I think nauseated but I don’t feel the urge to vomit just a lot of dry burps and all the other symptoms . I suffer from bad anxiety but I’m calm rn cause I’m tired and the symptoms are still there so I’m assuming I’m nauseated I was supposed to get my period on Saturday but it hasn’t come yet . I have safe sex and I’m not cramping currently . Could this be my period ?! Please help !!! I’ve been up since 2 am I. The bathroom freaking out cause I don’t know what’s going on. An I think I’ve been feeling this more if this is nausea
