Hey pmcc , Congratulations for your coming wedding !!

As SLOW says you can only decide the right thing for the two of you.
The only advice i can offer is that when i fell pg with my first lo i went on holiday to the dominican republic straight after and was very bloated ie struggled to do up my jeans and felt incredibly tired even though my af was due on holiday so i can have only been 3-4 weeks pg!!
It didn't ruin my holiday ( the place we stayed at made a fine job of that!!) but i wouldn't have wanted all that during my wedding or my honeymoon.
Not everyone gets the bloating and tiredness, i am just pg again and feel fine this time so it's just something to bear in mind.
Good luck for the Big Day !!
