Scotland, and I’m 6 months pregnant. Neighbours have stopped to tell me off for mowing the front lawn in my “delicate condition”, and that was with a Flymo. I bet I’d get a lot more lecturing if they see me with a pushmower!
I suspect I’ll end up doing what every mature, responsible grown up woman does, and ask my Dad for help 
ETA Alternatively, they sell spares on the Flymo site, which I’d have known if I’d bother to check before mini-ranting!
