Zofran not helping with morning sickness..anyone else?

Usually zofran has always helped me in the past with nausea. It even helped when I had really bad morning sickness with my 2nd child. I’m pregnant with my 4th and I have NEVER BEEN SO SICK!!!!!!!!!!!! I’m MISERABLE!! Like it’s to the point where I’m becoming depressed and so anxious. The nausea is so intense and lasts from the time I wake up until I go to sleep. I have yet to puke for possible relief. I’ve tried every single stupid remedy there is and finally resorted to zofran. Nothing has helped. I’m only 6 1/2 weeks. Please tell them this gets better!!! 😭😭😭 I haven’t tried phenergran or unisom/b6 because I figured if zofran isn’t going to help like it always has in the past, the nothing is going to.
