Based on your symptoms of vomiting and dizziness for about a week, it is possible that the transition from one contraceptive pill to another could have played a role. However, if your symptoms have persisted for nearly 2 months without improvement, it may be that you are not tolerating the current pill well. To alleviate your symptoms, you can try taking Gravol. If you are unable to keep down pills due to vomiting, you can consider using suppositories. It would also be wise to consult with your doctor to evaluate your situation further. Remember to stay hydrated to prevent dehydration from vomiting.
