bra help?

Caroline
so I wear a 32d and I'm spilling out of the top of the cup as well as on the sides where my armpits are 
even one of my guy friends noticed it (of course he'd be looking there😂) but 2 weeks ago I tried on my friends 32dd and it didn't fit right
could I have grown in 2 weeks or am I in between sizes? 
help!
