Happily I haven't felt off-balance at all while pregnant (although as of a couple of months ago haven't been confident doing certain things up ladders - painting is OK but drilling felt a bit dodgy so I got doop to do it instead) so cycling's felt fine throughout. TBH unless I'd actually fallen off it wouldn't really have occurred to me *not* to cycle, but then I am a bit peculiar :)

I think I've been quite lucky generally in terms of the physical impact (other than the first few weeks of 'orrible nausea) - am hoping that this continues for birth itself & post-birth recovery!
