Sorry you're having such a rough time of it George, I hadn't known about UTIs affecting pregnancy until reading yellow and portico's posts, (this thread really is as good as a book in some ways!), yet they seem to be quite common!
5 miles a day, eep. I thought I was doing well with my 2.5-3ish. I've had swollen feet and ankles for the last 2-3 weeks so wasn't sure if I should let it affect my activity but midwife said yesterday just to carry on as normal but remember to put my feet up at the end of the day. Pilates has been a godsend though, having less back and hip pain than I'd been having before.
