delaying salaah

Delaying Salaah due to illness

Q: During pregnancy I vomit a lot. It makes my Salaah late. Whenever I make wudhu normally, I vomit and I have to take rest and make wudhu again. My question is after vomiting my wudhu breaks? In normal circumstances I know it breaks but what about these continuous vomitings of pregnancy. I don't miss my salaah but this feeling prevails that I am getting late for it. Kindly guide.
