No noe gently but to be fair it was couple days before when I'd done last one, (ie Tues and labour thurs)
But no signs of it morning after either, I expect any remains would be passed in your first wee of the day.
Just in same area as people having sex just before labour starts really, mw's have seen it all,there's so much other types of fluids anyway,
Hope it helps, not everyone's cup of tea but if no harm then why not I reasoned.
Good luck however it turns out.
