It is normal to vomit when you're pregnant but it is not normal that you vomitted till 5 times. If you feel weak, can't drink and eat, please go to the doctor. They might give you an iv drip to hydrate you since you're carrying a baby.
The blood streaks are from minor tears in the esophagus, due to the force when you vomit. I had that too. If the anti-nausea medication currently doesn't work, you can tell your gynae, and they may change it to something stronger.
