I was so upset when mine appeared, like yourself they were late on in pregnancy and I thought I'd got away with it. My children are almost adults now and I've been oblivious to them for years.
As much as it doesn't feel like they'll ever look different now they really do change dramatically for the better over time.
When the weather is nice, get out in the garden in your bikini and embrace them, you'll soon see a difference and you'll gain some confidence getting back in a bikini without it being in front of other holiday makers and hopefully a tan, albeit a British one
.
You'll go away and hopefully not care less
