"i have been taking ortho tricyclen lo for 2 months now and have gained about 15 pounds.  this morning my jeans were to tight.  i am expecting period on wednesday.  i also experience a very heavy period last month, heavier than i have ever had. i also had cramping all month the first month and bleeding. it was very hard to deal with. i am not comfortable with the weight gain. i have also experienced mood swings. lots of crying about things that i would normally not cry about...stuff like the car didn&#039;t start!
