If youve been in severe pain for 8 hours, why are you not at the ER???? WE ARE NOT DOCTORS!
It could very well be another kidney infection. But you need to go to the ER since you are puking and i assume you cant kepp anything down. Go to the ER and see for sure what is going on. You dont want to get severely dehydrated over something you could get under control
You need to call your local triage in your birthing center. They can tell you. If you have another UTI it needs to be treated. Make sure you are well hydrated always. 32 oz of water about every 4-5 hours during pregnancy. If you don't like water make some crystal light. A UTI can make you very nauseated and can make you contract. Definately call.
