No matter what you do during pregnancy you always wonder 'what if', it's not the most ideal things for the bub 2 be but a once of thing shouldn't be an issue but def see your GP if you think something is wrong.

I didn't even know i was pregnant with Ava until after a MASSIVE Australia Day weekend, i had definately wiped myself out that weekend and upon finding out about Ava i was so stressed i had done her some harm but she is here and she is perfect (in my opinion ).

Try not to stress yourself out, take care of yourself and make sure no more binges, maybe a chat with DP about stress levels etc may be in order aswell.

GL with it all
