I suffered badly with hyperemisis during my pregnancies & was very worried about the babies not getting the nutrients they needed as Ihad nothing in my belly! The doctors kept reassuring me once I had the constant vomitting under control that the main thing is to get plenty of fluids. The baby will take what it needs from you no matter whatyou have or haven't eaten. I was also told to just eat what I felt like , even if it is only hot chips

Trynot to worry too much, I'm sure your bubba is growing nice & healthy

& in regards to when the vomitting should stop.... it doesnt have to. I had hyperemisis up until the day I gave birth with both my babies (& up until the day I lost my first baby) but some woman are lucky enough to avoid it all together!! It's just luck of the draw unfortunately. I do hope your vomitting stops soon for you
