Are There Any Side Effects Of Taking Norlevo?

Hey, just wondering about the adverse affects of the morning after pill Norvelo..I took it last month and then got my due period three days later..However the bleed was heavy and my breasts were very swollen and I gained 2lbs!!I had to then take another morning after pill last week and today I have the withdrawal bleed.Yet my breasts are soo swollen and I have gained 3lbs of weight..I know fluid rentention is an effect but shouldn t it go away once the bleeding has started??! Also I have read Norvelo causes weight gain but I actually have been dieting
