I'm 34 weeks pregnant and exercise regularly. I have uneven leg lengths so my pelvis is now feeling the strain and obstetric physio says it's a form of SPD but agrees I have no probs opening legs, swimming etc. It has become really painful to walk any longer than 10 mins these last few weeks, even with the girdle on so I've been going to my aqua fit and yoga on the bike. I use only quiet routes, cycle paths etc and wear a helmet and go v slow. I feel perfectly safe but some people seem to think I'm dicing with death. What's the latest anyone felt comfy doing this, if at all?
