abnormal uterine bleeding
"I got my first shot April 28th 2015. My period was supposed to come May 10th and didn't.. It was a week late and I've been bleeding and spotting ever since. I have bad mood swings and get mad over absolutely nothing. I get cramps all day every day and it's it so horrible. It's been almost 3 straight weeks of bleeding sometimes heavily and other times just spotting. I don't know if it even protects against pregnancy because you can't have sex if you're constantly bleeding! I would NOT recommend this to anyone, ever.  I have an appointment with my ob/gyn on Tuesday so I hope there is some kind of solution since I have to ride this out til the end of next month!"
