Yeah its normal, before i knew i was pregnant, i didnt eat or drink anything one day, i took a shower, fainted , woke
up throwing up. Luckily my boyfriend was in the shower with me lol. We called the hospital and they said to take a pregnancy test, that its a sign of pregnancy. We just laughed at them. Then a few weeks later, yup found out i was pregnant! Drink and eat throughout the day! Its dangerous if you dont!
