Well I have been on Yasmin for over 6 years.My youngest child will be 7 in November...After I gave birth and went to my 6 week check up I weighed 145. I now weigh 167. I am very depressed, an emotional basket case, and to top everything else off my period has been going on for 2 weeks. Does this pill cause weight gain and the rest of the side effects? I requested that I be put on these at my 6 week check up because I heard on TV that in Germany the women lost significant amounts of weight....HELP
