"so this was the first birth control i had taken and everything was fine the first three days, on the fourth day i randomly got sick, like hot flashes, lightheadedness, headaches, and vomiting, but after an hour and a half it went away. however from that day on i always felt a bit off and had lightheadedness and headaches for an hour or so every day always at a different time even though i took my pill at the same time every day. my period came early and i have never experienced such extreme cramping before. the only plus is that it didn&#039;t kill my sex drive and i didn&#039;t get pregnant"
