I'm 19, and am only 5 days into my loestrin24fe... and so far, I haven't had anything negative, Like, I always eat like a horse anyways, not that it hurts me, I'm 5'2" and about 130 pounds... I have noticed that it seems in the past few days, my sex drive has actually increased, like my boyfriend shows up, and it's all I can do to not rip his pants off. For me being on the petite side, my bra is like a B, and they look large on my small frame anyways, any idea how long it's going to take for their size to increase, if at all? I'm going into the Navy and I leave for bootcamp on the 26th, and if I end up with too-small bras there, it's gonna suck...
