The pill..?

I'm a guy so I can't tell you first hand the effects of any pill, but I can tell you that every different brand pretty much has a different level of hormones in them. Usually a female would bounce around, changing pill's until they find one with the right hormone level. Weight gain, increase in cup size, decrease/increase in flow during "that time of month", headaches, dizziness, cramps, early/late/shorter/longer period, amongst other side effects may occur.
