"i started taking generess fe 5 weeks ago. i bled for the entire first month. it just didn&#039;t stop. then i developed a stronger sensitivity to dairy products than i ever had before. the past 3 days have been unbearable. i haven&#039;t been able to keep anything down, i started sweating and nearly fainted a few times. i&#039;ve also thrown up 5 or more times. my mood swings have been really bad also. i have no idea if this does even help prevent pregnancy, as i needed a back up method for the first month. i&#039;m stopping this and making an appointment to see my doctor. there&#039;s no way i can live with constant gas pains and nausea and throwing up."
