Boobs:(

So I started birth control about 5 months ago and gained about 5 lbs within a week which is totally not normal for me because I’ve been at the same exact weight for the last 2 years. Anyways I went from a 34 d to a 34 dd practically overnight and that bra almost doesn’t fit either now but I’ve notice that my boobs have been looking saggier and idk what to do
