Hi. I am 5 weeks pg so very early days. With my first pregnancy I put on loads of weight and developed SPD in the last half. It's taken ages to get sort-of fit again and i've started doing quite a bit of running (up to 8 miles at a stretch). Am really keen to keep going as long as I feel ok, but have been given lots of contradictory advice. Most of the medical advice suggests it's fine as long as i don't run too fast or overheat (no danger of that!) but I'm paranoid about any risk to this pregnancy as am getting on for 40. Any advice? thanks
