"yaz gave me immediate bloating, gas from the day i started taking it. in addition, i had severe headaches and fatigue. my breasts grew a cup size which was bad to me because they hurt all the time and my boobs aren&#039;t small to begin with. i wanted to sleep all the time and was ready to be in bed by 7pm every night. it made me lose my desire to exercise. on a positive note, it made me feel a lot less anxious than loestrin 24 fe did. however, the cons outweighed the pros for me and i started loestrin 24 fe after and like it much better."
