Birth Control
"Was having some trouble with the pill i was on for a year and switched to the shot.  The first three months were great! No weight gain/acne and I felt great. After about two and a half months, I began to start bleeding and having severe cramps, so much so I could not stand up straight. At the height of my cramps, I discovered my body had shed my entire uterine lining at one time and it was the most frightening and gross thing I had seen. After the three months had finished, I had my period for seven weeks and am finally back on my regular schedule! Never again will I use this shot!"
