birth control
"I have been on this pill for 4 months. The first month my period was normal (for me - quite heavy), the second month my period was very light, and ever since I have not had a period. 
I still notice bloating and slight weight gain before my period, but no other side effects. Although the pill itself is quite expensive, it is worth it because I no longer have to buy hygiene products since I don't have a period."
