Hmmm, I hadn't heard about that but I guess it makes sense. My advice is to listen to your body. If you're having pelvic pain, then maybe you should shorten your rides or quit through the rest of the pg. I felt my best when I was riding--it was great. The last week, however, it felt as though the saddle was riding up between my sit bones--that's when I took up walking. Fortunately I only had 2 days after that until I gave birth.

Good luck with everything. I know it can be a frustrating thing trying to stay fit during pg. It seems like everyone has an opinion and they MUST share it with you. Listen to your body and you'll have a great pg.
