Waves, please, please get the idea that you're being a nuisance out of your head! You're not being a nuisance at all, you're in labour!
Labour can progress pretty quickly especially in pregnancies after your first, as I'm sure you know.
I expect you may well be having the baby as we speak, but if not, please don't be reticent about calling for help. It could all happen quickly and better that you have help to hand.
Thinking of you and wishing you and acrobat a speedy delivery (once you have help there of course!).
