Help! Advice??

Hi mommies! I’m currently 13 weeks and so far my sickness was pretty manageable...usually only vomiting once in the morning and now as soon as I hit 13 weeks it’s gotten worse ! Now I’m up to 6 or 7 times a day and I’m confused ? I thought it was suppose to subside not get worse 😪 it’s making me miserable I can’t even eat a damn banana or dink water since I puke it up 10 minutes later...really need some advice..my doctor isn’t worried just yet bc nausea means healthy baby but this momma is suffering! Any help is welcome ! Thank you !
