twinkle84, I think it would take a lot of stress to have an impact on the baby, more than the baby will take even more energy and nutrients from you directly and drain you even more. I'm of the theory that avoiding medication at all costs doesn't do anything for your well-being, so you have to find a balance. So there has to be a bit of a compromise! The paracetamol might not be helping you for pain relief but might help to bring down a temperature if you are brewing one! It might be that you will eventually need the anti-biotics, some GP's would have given them straight away. I'm sorry if what I said scared you, certainly not intended that way. I have to take co-codamol now and there is a risk to my baby's lung development, albeit a small one. So I try to only take it when I need it but there's no point in not taking it and being in lots of pain when I can do something about it and bring my stress and pain levels down.
I'm not sure I'm explaining myself very well, but if you are in that amount of pain and it's not improving then I'd go back sooner than a week. No point in putting yourself through hell! If you turn the situation on it's head and say had hypothetically been diagnosed with a urine infection, you'd have probably been given anti-biotics straight away.
