birth control
"I have been on a number of pills in the past (aged 28, started 18) - I have been diagnosed with endometriosis so my reasoning for remaining on some sort of hormonal BC was vital to reduce the symptoms. 
I was placed on Yasmin after experiencing major mood swings/depression on Yaz. Yasmin seemed to reduce these mood swings considerably. Since Yasmin my periods, although regular, have been light and cramping has been reduced/completely absent. Amazing! (5  years on it now). I have been getting migraines for the last 2 years so might have to change my BC again. One's body changes with age, I guess our meds need to too."
