Can't speak to the pregnancy aspects, but just be very careful since you truly never know when you are going to fall. I took a very bad fall in April when two "we mean business" dogs ran out into the road out of nowhere at my husband and me while on a training ride, and broke my pelvis in three places. I never fall under normal conditions and ride ~4000+ miles a year normally as well. Everything can change so quickly when the unexpected happens, so I would be leery of putting a pregnancy at risk.

Sorry to be a wet blanket; I just have my formerly rose-colored glasses tinted a slightly different color now.

Welcome to the forums, by the way!
