Help!!

I'm 30 weeks, up until a couple weeks ago I've had my morning sickness under control (thank God for the calm of the second trimester) but lately I've been throwing up and feeling very ugh. Example: I've thrown up EVERYTHING I've tried to eat or drink today, a total of 4-5 times since I've woke up at 8am. Now I've tried it all, ginger tea, sucking lemons, eating crackers, nausea bands, etc! Nothing helps, I need remedies.. What's worked for you ladies?!!! Pleaseeeeeeeeee im miserable I'm open to anything at this point😩😥 my next Dr appt is Monday so I just need to make it till then and maybe my doc can prescribe me something
