Working and contractions

I am currently 35 w, so working for another week before i go on leave.

Its so weird when i am in the middle if talking to someone in a meeting and i start to have contractions. I can feel the belly getting tight and having back cramps but i still have to keep a smile and continue speaking as if nothing is happening..

How do you gals do this? Do you hide or just say you need a break?

Luckily its not consistent right now else i would have to rush out of the meeting
