Alice - I have been pregnant five times and each one was a little different from the other so feeling different than the last pregnancy indicates nothing. I don't get breast pain until around week 7. I still think all your other symptoms sound spot on. I think you are so stressed that it's best not to test yet because if you don't get a second line then you will be more stressed and it could be for no reason. I wish I could do more to help. I hope you have a lot of support around you and there is someone (other than just DH) that you an share all this with.
