Oh no frankie! I hurt my back the month we conceived, had to bd high on codeine to be able to cope with it! I was moving something about 1 foot across the floor, wasn't even heavy but I just felt something go and it was so incredibly painful, never known anything like it! I was frozen to the spot and felt sick, hubby managed to get me on the bed (with lots of tears) and the doc gave me codeine which helped me move about (I couldn't move without it!), the moving around actually helped to ease it but I couldn't have done it without the painkillers. If its still bad on Monday morning see what the doc says as they may be able to give you something stronger than paracetamol that is ok to use when pregnant. Fingers crossed though that it doesn't come to that. Either way, you really have my sympathy! X
