Whoa!
I was considering starting the shot, but after reading the post in hear....I will JUST SAY NO!! I heard about the weight gain, but hair loss too

That is a double whammy!
Just add my .02 cents...
I am currently on Ortho-Tricyclen and the only side affect I have experienced was....CLEAN, CLEAR SKIN !

And it happened in less than a month. I have not experienced any side effects such as weight gain, hair loss, etc.
