"been on the shot for 5 months now and over all i don&#039;t mind some of the side effects (to me they seem mild). the most annoying one is the irregular bleeding, for example: i&#039;ve had 1 regular period since the start, then it stopped the next month, then i bled (spotted) the whole next month, now i am just spotty throughout the month on and off. i still get pms symptoms, but they&#039;re not as intense as before use.  it did not help clear up my acne (existing hormone issue) but it is less of a hassle than the pill. i did increase my vit. b intake with this method (as recommended). i rather deal with irregular spotting than a child so i will continue use."
