birth control and multivitamin interaction??

prestyn

i started taking zovia about a few weeks ago, and the two times i took a multivitamin i had woken up naseous the next morning, but i thought it was just the birth control alone, and i was getting used to it. yesterday i took a multivitamin at about 6 pm and i woke up this morning naseous and threw up a few times. could there be an interference between multivitamins and birth control, or is it just a coincidence. btw i feel fine now.
