I have been taking Yasmin for about 6-7 months due to abnormally long periods after the birth of my second baby at age 37. I also have a tumor in my uterus that might be causing painful intercourse, so the Dr. said to take it for three months straight and then have a period. In the meantime I have noticed severe sotmach cramps and diarriha (how ever you spell it) since October. Funny thing was that the first round I was suppose to take 2 months of Yasmin and at the end of the second month have a period, then do 3 months and have a period, but I noticed that on the 2nd month after I had my period (which I acutally stopped taking Yasmin since the white pill is only a placebo) and then started back on the next round of the 3 month cycle I started having real bad stomach cramps, etc. I am about to have my 2nd period of the 3 month cycle and I won't take the placebo and see if my stomach feels better. If it does, then I am stopping Yasmin. Another note, I take Yasmin at night and wake up at 1 am and 4 am like clockwork with stomach pain. I will keep everyone posted after the "placebo" period to see if my stomach gets better. I anyone has any similar symptoms, please let me kow. Tammy.
