its perfectly normal hun 
sounds like you’ve had overs….is that right? cos unders are squashed when they’re first done and look like mens pecs!!
i’ve heard a lot of girls liken their boobs to those bras madonna used to wear in the 80’s!
it’ll take maybe a week or two for them to start showing their true shape….take pics every cple of days and when you look back on them, you’ll be amazed at just how quickly they DID change xx
