birth control
"Have been on this for about 5 months. At first breasts got larger (about a cup size) and my period got lighter. No other side effects however recently I have been getting very nauseous  either a few hours later or the next morning even if i take pill with food. It's to the point where I am unable to hold a conversation with someone because I feel lie I may throw up. However I do have a very sensitive stomach so it could be a combination of the two."
