I am 11 weeks pregnant and have this very bad pain in my lower back. It is in my tailbone and it sometimes spreads into my right leg (the back of it and runs to almost the back of the knee). I have no bleeding and feel very pregnant. I have also had a scan which showed the baby is in the right place and is the right size and nothing to worry about. I am really worried as I am actually not in UK (in a war zone in fact) and I worry about what will happen to me as I go along and get heavier. BTW, I haven't even put any weight on at all in fact I have lost 4 kilos in last few weeks. Any help is highly appreciated.
