"being a newlywed, i was looking for a birth control i could trust, i originally was on the pill, but i have cyclical vomiting syndrome, i&#039;ll basically have cycles where i vomit uncontrollably, so during a 3 week cycle, i realized the pill would not be a good fit for me. so i switched to the shot, the second month i was on my period for a full 30 days, which i was told was normal, after that i haven&#039;t had a period at all, i have had no side effects, no weight gain, and most importantly no pregnancy scares."
