PMS Nausea HELP

This is about to get gross, but I know some of you are pregnant and deal with nausea/vomiting daily so hopefully you can help me. 
so I get nausea before every period. 
I am not pregnant. 
This time the nausea is really bad and my stomach is just so upset. i decided to make myself throw up because if I go ahead and get it over with it helps with the nausea.. Usually I have to shove my fingers down my throat to throw up (I know that's horrible and I only do that when I am really nauseas and need to puke and I don't throw up every cycle) this time all I had to do was lean over the toilet and bam. And I couldn't control it and puked until I was dry heaving and had tears rolling down my eyes. 
I am slightly miserable right now and it did not help my nausea. I don't have any nausea meds.. I actually had zofran prescribed to me by my doctor for my PMS nausea but I am out of it. Right now I'll try anything, I'll drink or eat anything that will help soothe this
