Thanks myturn. Last time I tested was yesterday afternoon about 3 pm and the line was the strongest of them all so far, a lot stronger than my morning one. For some reason my morning pee tests are not as strong as my afternoon ones....Anyway, the cramping and back ache returned yesterday afternoon/night. I haven't tested this morning, I think I'll just wait till BT. I know there is a line there, it's now a question on what's in the blood and that can only be known from the BT, enough HCG or not. I now realise the digi test is not as sensitive as the ER, so maybe that's why it hasn't picked up the low levels.
