No but it's exactly the reason I didn't have one, my mum wanted to throw me one and would have done just this which I wouldn't have been happy with either. I already have everything too! If you can't get out of it I'd just show your face for a bit, smile politely then fake tiredness and retreat to your bed for a nap lol
What can they say lol we pregnant ladies must make sure we get our rest of course :) I've said it a couple of times now to avoid visiting people I don't particularly have tolerance for that day haha
I definitely like your kind of answer! A nap always sounds amazing to me. I'll definitely be taking that advice
