You can get pregnant after being sterilised, there is a 1 in 1000 failure rate. If you were sterilised during your last caesarian section then it may be more likely to fail than if you waited 6-8 weeks before having the procedure done.
If you get no joy from your GP then either telephone the secretary for your consultant who looked after you during your sterilisation and get an appointment with the consultant, or make an appointment to see the midwife at your GP surgery.
Your backache may well be caused by the fact that you have had children, especially if you had a twin pregnancy. It does take a long time for your body to get over having babies, which is why we don't recommend that people have consecutive pregnancies without at least 12-24 months rest in between.
Hope you find out what the problem is soon.....
