I am just over a week into my fourth packet of Yasmin. First two months were OK. Last month started to have occasional leg cramps, feeling tired, stomach bloated, sore breasts, very little interest in sex, mood swings and bouts of nausea (nausea used to be just after taking pill every day now it comes and goes all day. Only had slight brownish discharge for a couple of days on last week of non-active pills. Pregnancy test negative. Thinking of changing to a lower dose pill (20). Can anyone offer advice?
