Well, I spoke to my midwife this afternoon who told me to go into hospital. They monitored bubs - which took ages as she didn't like the monitor and kept moving away from it! But eventually they got a good trace and she is fine. They checked me out and said I have severly strained my muscles but not torn them or given myself a hernia - thank goodness! They have given me some stronger painkillers, panadol was doing nothing, and told me to rest tomorrow. As I finish work at the end of the week it means I have only 4 days left of work

Thanks everyone for your help and suggestions - most appreciated
