Babymoon and swimwear

Katie

Me and my boyfriend are going on a babymoon in five weeks and I want to start buying swimwear/ clothes before they stop selling them for autumn time but I’m not sure what sizes to get.

I’ll be 19 weeks tomorrow and still don’t have much of a bump just in the stage where I look like I’ve put on a bit of weight. I don’t want to buy my regular size incase they don’t fit by the time we go and then it’s too late to return them.

I was just wondering how much you all grew from 19 weeks onwards. I know everyone is different but just to give me an idea of how much bigger I need to buy things
